RKM Motorsport - Tuned Tuners - May '13

are you sure it wasn't wheelspinning a bit before the settings? Slight slip of the front tires is still spin/slip, just much more difficult to notice. ;)
Yeah, that's possible. With all the understeer on the default settings, the front wheel slip might have flown under the radar.

But I did find that the RKM tune had the rear swinging out wide if I wan't more gentle on the throttle, so I think some more horsepower at the front would pull it straight and make for faster exits. But your way is more fun, so please don't change it :cheers:
 
I tried out your 908 Killer Whale tune yesterday, too. The car (well, used the Peugeot Total version but apart from the colour scheme I guess there is not much difference, right?) was one of my relatively early purchases and has seen me through all the races requiring that type of machinery.

Using a DS3, at my n00b skill level, I found it to be borderline controllable but nevertheless fast. I could win every single individual race after a couple of attempts (restarting after spinning out) with all aids off and ABS on 1 but would find winning championships, where I needed to drive 5 clean races in a row next to impossible. With TC on 5 and ASM on I could win those, too but a lot of the time I was blocking and honestly holding the field up (could easily get to first but it was quite a challenge to stay there). And this was without the extra power from the added turbo - I figured the car was too much of a handful at the stock P/W for me.

I subsequently tried your tune yesterday - as intended without driving aids. And what a difference! I could do Indy without lifting, getting me the first 39 second runs I have ever seen. Not necessarily a comfortable experience for the Indy 500 (not lifting means a much higher level of concentration to nail the turn in points, and probably wears tyres out significantly faster) but I managed to lap cars in the 5 round race already :bowdown:

Took it to GVS next (lvl 19 Gran Turismo All Stars race) and the embarassment (of the opposition) continued. Funnily enough the Chapparral 2J managed to hang on best, with only 15secs behind by the end of the race, while the Pescarolos all took more than half a minute longer. And this was with me occassionally hitting the armco. The car is really so easy to drive for a 900bhp plus moster on this track. It easily gets you to 200kmh plus before braking after the third tunnel, the tail never really threatens to brake badly lose, not even accelerating out of turn 3, or the penultimate corner. I even got a rear wheel on the grass twice without any brown pants moments. I am sure biped opponents would give me more trouble than the AI but still - the car is likely very, very hard to beat around here.

Did the Nordschleiffe after that. While I like the circuit, I always felt that driving a full on Le Mans racer on it was way beyond my skill level. First off, the same still applies ;) I will eventually invest in a wheel and who knows, with time I might bring my times down with such machinery, too - at the moment I am still more of a pale faced passenger than properly in control of the 'Whale'. Nevertheless, your settings allowed me to at least comfortably finish the race in first (if not quite so crushingly as at GVS - but then I had at least 5 offs with 360 degree turns). As long as I managed to keep it on tarmac, I was gaining several seconds per sector. When I got it off, I would lose 5 to 10 but not to worry - could always regain it easily enough. Here, the car will definitely not tolerate a wheel on the grass, and being pretty wide means taking good care not to drift too far to the outside of a curve becomes essential. As with the other cars from your garage, lowering it substantially seems not to have harmed the bump absorption capacities too badly and it rides well both on the Ring, as well as at Le Mans.

Speaking of which, that was my final testing track. I drove it in the 3 lap lvl 24 Dream Car challenge. I knew the opposition was not up to much - at least there was the XJR-9 LM to keep me a little bit honest ;) Or so I thought - turns out it was faaaaaar behind, as well. Of the three laps I managed two in the 3.18.xxx range, so the car is nothing if not effective. I did have an issue with turning in to the Esses but that is more my problem of missing the turn in point that the car's fault - when I got it right on the third try it certainly worked like a charm. A completely unexpected development was that the indicated braking zones were now spot on - previously I would need to brake half a second or more later than indicated in order to avoid stopping to soon. I am not sure if that is a result of your new settings, or one of the more recent GT5 patches, just thought to mention it.

In addition I found the first braking zone for Indianapolis to be strangely longer than I am used to in comparable machinery but it could be that my closing speed it that little bit faster, too (I had no saved runs to compare it to). In any case, it is not a problem and I never lost any carbon fibre around there. The technical section after Arnage is not an issue, either - as long as you don't get an outside rear wheel on the grass or gravel, you should do just fine.

While I am certain that an experienced racer with a full wheel setup can shave extra seconds off my time, I have to say I was very pleased with the car here. If I ever get the time to plunge into the 24 hour race at this circuit, the car will certainly be my first choice. I would recon it is hard to lose against the AI with the added confidence your setup provides, allowing you to extract the most out of the car.

So in the end - strong points? Super steady under braking, no weaknesses in terms of cornering (as far as I could tell), largely quelled on-power oversteer (i.e. you can pretty safely apply full throttle when exiting corners, without fear of consequences - something very far removed from the original) and a comparably (for a car of the calibre) stress free driving experience, making it very well suited to endurance racing.

Finally, I gave the car to my posse of Bob's, to see how they would fare in the 24h Le Mans race. It started in the wet and the lvl 36 lead driver immediately lost places at the start, then I managed to coax him to first place by Lap 3 and had him build a bit of a lead, when I next checked an hour later, he was down to 5th, and finally I abandoned the attempt 90 minutes in. I was not going to sit around 24 hours to constantly guide him and in spite of the better speed the car had, the B Spec drivers simply did not know what to do with it - the best lap was 3-4 seconds faster than the rest, leave them alone for 2 laps and they do 12-15 seconds worse than the fastest Audi. This is not meant as a criticism of your tune at all - just as a word of helpful advice - Bobs, at least at that level, simply seem to need something much faster if you want to ensure they win (and do not have loads of time on your hands to constantly guide them).

Im looking for a non-rm ZR1 setup.. something to keep up with the Acr's, Ferrari's, Lambo's and R8's. I really trust You guys at RKM, i love every tune Ive tried from you guys so far. I would gladly send you guys a ZR1 to tune if you guys have the time. Oh and Ive read somewhere on this forum saying that using the rm tune on a none-rm ZR1 would be alright, not to sure about that. anyways, hope to hear from you guys soon. thanks
 
Your car, up to you. :P Just that mine will always be pink and will never be driven unless someone else in the room is using an R35. :lol:

I'm gonna paint it in either one of the M.N.P. R34 colors or the Opal Black color. By the way, should upgrade it a bit before leaving the job of adjusting settings to you?

And oh yeah, I forgot. We all know that the GT-R's are track monsters, right? That's my request, an all-around setup that makes the R35 rip through the whole track in an instant. Something that can still handle well while maintaining its crazy acceleration. Maybe this is a setup for the 'Ring, is it?
 
I hate to keep buggn you but I bought the GTO 5.7 Coupe. The factory tune is surprisingly not bad but after I installed all the upgrades it just doesn't cut it. I would appreciate any ideas.

Tuner Comments:
This is the F430 Stradista. You'd think Ferrari would've given up on the 430 now that the 458 is out, and you'd be right; this car has no actual input from the original manufacturer. Why? They like to build fat cars, we don't. Everything has been either heavily lightened or removed, including the electronic garbage which previously polluted the car. The result is a car that, while only slightly more powerful than the 458, wipes the floor with anything and everything Ferrari's ever made.

Haven't taken this ride out to the track yet but I did want to point out that when we were in the garage working on her we had to set the top speed to 137 then adjust the final to 2.5 to get to the gear ratios that you've listed here.

I'm giving her to my test driver today for a little break in then I'll make my final tweaks and bring her out to the track for an extensive shake down in preparation for use in my Monday Night Endurance Series. I'll have a full review up for you post race.

Thanks!
 
Review of the Honda Integra Type R Part 1
This is the first part of my review of the Honda Integra Type R. I have been testing on a course maker track (Eifel Theme) to test its ability to drive on a road without many bumps. First of it is a very fast car a bit over 300 BHP there has 999 KGS to move around. The car accelerates very fast and smooth when the wheels are pointing straight. The first corner on the circuit is a double right-hander where you just touch the brakes into the first one and the brake heavier for the second. In these corners the car has a slight tendency to understeer when it is braking and turning on the same time. I would personally prefer a more oversteering car on the way in and out of the corner. Maybe making the spring rate higher at the back and setting the brake balance to 5-8 or something like that. I need to say: I don’t have any experience in tuning fwd cars :) on the way out of the corner it has nearly no understeers only when you floor the throttle in slow corners is has powerundersteer but you cant do anything about that I think. This is as said the first part of the review I will do some testing on the Nordschliefe and sorry for my English :)

Thanks for the review! Braking and turning at the same time is something that a FF cant handle doing, the tyres just get overworked and you end up with understeer. That reminds me, RJ used to have a DC5 Integra on GT4 with lots of oversteer, crazy car. :lol: Looking forward to part 2! 👍

Also, R32 Skyline GT-R and Yellow Hat Supra updated.
 
I tried out your 908 Killer Whale tune yesterday, too.

Now that's a review. :eek:

Sounds about bang on really; if I'm honest, I built it as a time attack car as winning a time attack was the only way to keep it (obviously I won :sly:), the diff was probably the single biggest time reduction of everything I did to it. It does cause slightly more wheelspin than default or any higher value for that matter but it generally eliminates the car's want to kill the driver the instant too much throttle is applied... And even on the race softs it eventually wound up on, "too much" was really very little in the lower gears.

Interesting about the braking seeming to be worse though, I'll probably look into that.

@Bri-Y: Explanation for gearing not matching up explained via PM, as you already know. 👍

@uMadson?: Yep, build it to the specs you want, then I'll fix the setup. :P
 
Before you spend significant time looking into braking, I would just like to point out that the braking zone (using the driving line) is now spot on, whereas before it was a bit conservative. Not sure if the new settings allow GT5 to make a more precise estimate, or whether there was a change in software with one of the later patches that corrected this. Not checked with enough cars to give the statement. What I am not saying, as far as I can tell, is that the braking zones lengthened (might be the case but I still rely on the driving line more than on track features for determining the braking zone).

As for the specific case of the first braking zone into Indianapolis, the closing speed would probably be around 10-15 kmh higher than in the other cars I have tried there recently, so potentially the difference was just enough to necessitate a longer braking zone :)

But if the car gets even faster, be my guest at looking into the braking :D

The Bobs just finished the 24 Hours of Le Mans this morning, so I should be able to try another one of your creations this weekend, work permitting. In which case I will gladly write about it, unless the 'war and peace' length reviews are already scaring you off :lol:
 
I tried out your RX-7 R400 tune back when the Seasonal Event required one and was very impressed but understeered a bit too much for my liking so I changed the Roll bar settings. I was absolutely blown away with how nimble and balanced the car is!

I initially thought 400hp would be too little but after passing many cars online and beating many of my own time records I am thoroughly impressed with the car as a whole. I love how you can power out of a corner without any wheel spin and how easy it is to fix mistakes with very little steering.

Great job!
Highly recommended!!
 
Kusabi Evil C updated. Murciélago LP780 SV next. :D

Edit: Done! BLiTZ ER34 Grip Tune next.

I tried out the RX-7 P400, and it's a good tune, but I think that it understeered to much. However, thanks for so many great tunes. :)

So far I've dialed out quite a lot of the push versus the current posted settings but I'm not going to "fix" it until I'm noticeably more satisfied with it.

I have been testing on the Nurburgring Nordschliefe. And I will start to say I am very impressed is the car tuned on the ring? Because it steers so nice on the very bumpy track. It is only I the very fast corners it understeers probably because it has no front downforce. That is not the tunes fault because there is no option to give it any. I will as you probably now have a quit oversteering car and the Integra don’t deliver that(probably something to do with it is fwd) but on the very positive side it has nearly no understeer. It is very easy to drive and steers beautiful round the many bends it feels even better the rm’ed version. But again I would have preferred more oversteer most under braking I miss it I normaly sort of get the back out so the front steers in and I cant do that in this car. Overall I will say this is the best fwd road car I have tried in gt5 so fare. Good work keep it up. Pics will be up later this evning.

here is some pics i took of my self driving both car 1 with wheel the other with a ds3 controller.

I already replied to part one so I'll just answer part two now. 👍

It was tuned on Trial Mountain so the suspension can cope with bumps. Front downforce is something I'd like added to every car with an aero kit, since it's essential in keeping some cars from understeering. Although without it, the suspension settings become more refined to make up for the lack of downforce. :D

Glad you liked it, thanks for the review! Looking forward to the pics! :D

In other news, the BLiTZ ER34 Grip Tune is done, and I will be finishing off the rest of the roster tonight, minus the SP1. Until I can borrow the SP1 from it's owner, I can't do anything about it's gearing.

Edit: Finished! :D Every car (minus the SP1) in my list has now been updated. Have fun with them guys! Now excuse me while I tune some new cars. ;)

Having several times looked at it, and with it being the by far fastest car on the 1st time trials (the only ones I tried out so far), I figured it was about time to give the Evil Kusabi a try.

As usually I started off by installing all the required components and trying the car as is, without applying your settings - the exception of course being the gearing. Having never driven the car, your description and the Time Trial fame is all I had to go on before starting. Well, looking like it was made out of a Stormtrooper helmet certainly raised expectations somewhat. ;)

My first experience was the lvl 15 Tuner Challenge race at GVS, a track I am quite familiar with by now. I really need not have worried. I was in first before the first tunnel on the starting lap and it never really looked like the position was endangered. The late charge by a Yellowbird was nice but taking about half a second a lap off me with 8 or so seconds behind, there was little to be afraid off. Well, for me, anyway :)

The car was pretty sweet out of the box, with enormous grip, practically no understeer and while no wonders can be expected from its 270hp, these are at least delivered in a fairly linear fashion and at this track the power certainly sufficed to best the opposition. The only issue with the car stock, and I am splitting hairs here, was a bit too much understeer on accelerating out of the third corner. Not dramatic but a bit surprising, given that it occured nowhere else.

The best time I achieved was a 1.58.1xx, which is pretty close to the times I set with your NSX (albeit with Sports soft tyres).

Applying your settings next (I was actually thinking of lowering the power, to make it fairer on the opposition :P) I went for another go. Initially there was not much difference to be noted. The washing out of the front when accelerating out of turn 3 was now much better controlled, however I needed to concentrate more in the section between the first sector timing post and the first tunnel. I somehow managed to get too closely acquainted with the armco there once or twice, which did not happen with the stock settings. Still, if I nailed it, the times were as good as with the stock setting. And these were pretty spectacular - I would need to check back but I recon the speeds achieved in that section are some of the best I have had with any non race spec car.

The other section where the car is simply amazing is accelerating out of the second tunnel, basically from the mid point on out. The third tunnel is also really easy, with speeds of 140 kmh inside - not something to be scoffed at for a FF. :bowdown:

The S curves after were taken at a very good speed, too and the front end grip was good enough so that I never needed to use the concrete section next to the track at the penultimate corner when accelerating out there. The final turn also requires no lifting and gets you onto the final straight at pretty sweet speeds. My best lap was the last one of the race again, recording a 1.57.0xx time, so just over one second faster than with the stock setup. I guess given that the car felt so good in the original setup already, this is quite a significant difference. Most of it, it seems, came from a better first sector, with the other 2 or so tenths coming in the third one (the middle one being pretty much equal as far as times go).

The next track I tried it on was Suzuka. Being a faster track than GVS, I was a bit more worried about the power deficit to the other Tuner Challenge cars and on the start finish straight I had two cars pass me at warp speed. After the 1st and 2nd turns I was already back in fifth, though and the S curves got me up to 4th. Managed to pass a Nismo Z (too quick to check which one) in the first Degner for third, and got up to second on the exit out of Spoon. Speaking of which, the exit speed out of Spoon was pretty impressive, too.

The car was good through 130R, too and as usually, I could make up time in the Casio triangle. Unfortunately, finishing the first lap first did not mean staying ahead till the end of the start finish straight, this time both a Nismo and an Amuse GT-1 passing me. Generally those could easily be dispatched in the S curves but as opposed to GVS, the car seemed to understeer more at Suzuka, with both Gyaku and Dunlop (the latter especially) requiring a careful approach, not to plow on too far to the outside of the corner, losing time and potentially hitting gravel.

The exit from the Hairpin curve also needed patience before applying throttle, otherwise you'd understeer out, and as opposed to usually, where lifting or a slight tap on the brakes would tuck the nose back in, it seemed not to happen at this turn.

To cut a long story short, I could win against much more powerful opponents at this circuit, too but am not so sure that a human driver in A GT-1 would not have passed me fairly easily.

I then decided to take it to the Nuerburgring to see what it would do there. I found no race where I felt the car would be fairly matched to the opposition, so in contrast to my regular habit of testing the car in A spec races, I went for a round of practice.

I was feeling fairly cocky by this point and thought the car would be fairly murderous in the Eiffel, just like previously. The result, I am sad to say, was a bit of a mixed bag. The grip was there, the speed was good but I felt on several occassions that the car was most certainly not tuned for this track (I might of course be mistaken).

While the car handled both bumps and kerbs at Suzuka and at GVS without a problem, so much as looking in the general direction of a kerb at the Nuerburgring could mean the car skipping a meter or more in the opposite direction. In the end I decided to just steer completely away from them, as they disturbed the handling way too much. I guess the maximum lowering of the suspension also had something to do with it and a softer setup would work better on this track.

I also felt the back did not really follow the front perfectly on the bumpy surface here - I often felt the car became very lively with the back breaking out on several occasions. Had such 'moments' at Hatzenbach, and then even more in the second part of the track, when elevation differences come into play as well. From Eschbach to Schwalbenschwanz it's a really wild ride - it seems the suspension cannot quite cope with track imperfections, elevation differences and the stresses of the engine all at the same time. The fact that the back seems a bit snappy here means I would have totalled the car on several occassions, were PDs damage modelling a bit more realistic.

Another place where I felt too much braking and associated time loss was required was at Klostertal - in order to completely avoid the kerb on the inside the corner (which would launch you into the armco opposite) you needed to brake quite a bit - in spite of the car having sufficient grip to carry you through the corner full throttle otherwise.

Finally, I decided to be a bit naughty and check out the car with sport soft tyres instead of the race softs as originally specified. In order not to (figuratively speaking) kill my self in the attempt, I did this at GVS. The car still worked after a fashion, of course not nearly as well as on race softs. There was more understeer and corner exits required some more patience before throttle could be applied when compared to the race soft tyres. The final corner could no longer be taken flat out either, leading to the entry speed onto the final straight of ca. 10 kmh less than with race softs. The first sector was only about a second slower, however the second one, previously the warp speed one of the Kusabi, was significantly off, with the third accounting for the rest of the difference.

I guess I could shave perhaps another half a second off with my driving and the DS3, if I practiced some more, as is, we are talikg times in the 2.05.xxx area, so not that different from your '08 CTR with the turbo removed. As said, it is clear the car was made for race softs, so this is a bit beside the point, just as an aside, really :)

So final verdict? Works wonderfully on smooth, preferably curvy tracks - the grip there really is phenomenal. It is probably a solid beginners car - if we are not talking really bumpy, it will flatter any driver and the fact that it has enough grip to handle braking / accelerating and steering at the same time, and that stability under braking is good, while mashing the throttle on corner exit usually does not produce much understeer, I would certainly say that it is the easiest novice car of your tunes that I have tried so far. The fronts never seem that overloaded to prevent further inputs and it really handles sharply for a FF. Care needs to be taken on bumpy surfaces - i.e. Nuerburgring, where I think that a softer setup would suit the car better. But then again I am no Nordschleiffe fiend, so take it with a pinch of salt. My best time was in the 7.18.xxx range, with some improvement to come. Another suggestion for that track - the 6th gear is too long - I struggled to get to 270 and above 250 the car's acceleration with the existing 6th gear is really glacial.

In any case, a fun little car and certainly not to be underestimated - the force is definitely strong with this one ;)

Review of the Honda NSX LM Road Car.

I have tested it on two circuits the custom one also used for the Honda Integra Type R review (Eifel Theme). My first idea was to Review the normal NSX but then in my UCD this car showed up and I bought it immediately. When I saw the settings I was very surprised by the racing soft tyres very unusually for RKM tunes. So I thought this is going to be very difficult to drive when they have mounted so soft tyres. First I took it to the Eifel Circuit with standard settings (all parts fitted) and I was very surprised it handled very well had tons of grip and a very sharp turn in to corners. But it had also problems the back was very nervous under braking and if you put the throttle down very hard a bit to early you have no chance of saving it from a spin. After the very positive signs from the car I changed the set up to yours. Right away the car was even better the turn in is so sharp someone will probably say it is to fast but I love it. It was rock stable under braking and I had even more grip. You shall really press on to get any understeer it only happens if you go stupidly fast through a corner. The improvements in handling and other things improved my lap time by 1.6 seconds. That is very good for a so good car out of the box and then makes it so much faster. The only problem with the car is the tyres grip because if it begins to slide you have no chance of holding it. Another problem is the gearing I think it is to long for most circuits but not a big problem. I think I could have been faster if the spring rate was a little bit harder at the back. But no big floors with this car it is my favourite tune so far but please make a tune to racing medium or hard tyres.

Here are my pics of the car hope you enjoy them took me sometime to get the car look like it does. Unfortunate it is not the best looking standard car.




Hope it is a useful review and keep up the good work.
 
Problem 1: No way in hell is Lord Zed, the STi 400, RX-7 R400 or Mazdaspeed RX-8 slower than Green Meanie. Particularly not by that amount.

Problem 2: What are you on about adjusting the Ikeamobile's gearbox for? It's supposed to have the stock gearbox, not the FC unit.

And the above absolutely shocks me... Because the separation between the Stradista and LP710 is about bang-on but the LP came out quicker despite being massively more difficult to drive... When using the correct tires.

Having several times looked at it, and with it being the by far fastest car on the 1st time trials (the only ones I tried out so far), I figured it was about time to give the Evil Kusabi a try.
Thanks for the huge review! :D The car was a request tune so I concentrated on tuning it for racing tyres, which means performance on sports tyres gets neglected. I would've used sports tyres myself, as it's only got a small amount of power, but as said, it was a request tune. You've pretty much nailed everything about the car. It is suited to smoother tracks, since it has no downforce and no weight. :lol: Once it gets bumpy, the Kusabi wants to take flight. Glad you liked it! :D
Review of the Honda NSX LM Road Car.
Thanks for the review! Glad you liked the car. Again it was a request tune so I've had to obey the owner's wishes to use racing softs. It's stuck to the road like glue and if it slides, it'll snap instead of drift. The long ratios are so it can be used on longer tracks like Fuji and SSR7, two places where this NSX LM can really stretch it's legs.

Also, noted about tuning for racing hard and medium tyres. I'll see what I can do in the future. 👍


Thanks for putting the time in to do a lap time comparison like this! It's very interesting to see where our cars do against their siblings. :D:tup: I love how I have the best 2 awards and RJ has the worst 2. :sly:

Thanks, but as I said there just a second ago, I'm going to have to revise the lap times, so the review (this time, a little more 'correct') will be back soon :)
Nice pics by the way :lol:
 
Chevrolet Camaro SC550

I usually overlook American cars because they are bulky and not-so-good through bends. But knowing this tuning firm works, I decided I would treat myself to new American muscle at it's baddest. After installing all required modifications and the respective tires, I immediately took it hot-lapping in the Nordschleife. I don't know why, but every car that rolls out of RKM seems to have a magnetic attraction to the Green Hell.

Anyway, onto the actual driving. Without applying a single setting change, the car immediately felt... everywhere. Insane acceleration with insanely low top speed, coupled with more all-corner oversteer wasn't a very nice ride. I ended up wearing the tires before the car could hit 200kph. So, onto the settings. Some seemed odd (like the 1/1 anti-roll, but you would know) but were applied anyway.

After that, another track session. The change was enormous. Literally. With the much longer gearing, the car wouldn't reach top speed within a couple hundred meters, while still retaining that brutal acceleration one would expect from an American muscle car. I really like how 3rd gear is set up. Why? Well... the car obviously still had corner oversteer (tends to happen with 530hp) even with neglectable amounts of throttle, but this time this oversteer felt fun. Controllable. And what did it remind me of? None other than your very own 300ZX.

Oh yeah, corners. Braking feels very solid except when you're trying to brake from 230kph, uphill, in a bumpy surface. I learned to deal with it, because it can't simply be mash the brakes and go your way. But the brakes need to be pampered. That way they won't end up killing you. Anyway, corner entry. The car isn't very fond of threshold braking. But under no braking, the car was not reluctant at all to... turn. Those apexes were being hit with such ease and grace for such a brute of a car, that I ended up overdoing it. I convinced myself I was on Race Softs somehow, because I saw some numbers on that speedometer that didn't add up. Nope, Sport Softs. Hm. RKM set out to recreate max grip with less grip. I was very impressed by that. Of course, not on every corner, but of those, 100% were taken 10kph maximum below what I usually corner with Race Softs (hope that makes sense).

And, for the first time in my life, I encountered understeer that oversteered. The car would understeer, go into a drift, and somehow convert that into cornering ability. Chances of going off track were greatly reduced. How does this happen? I have no idea, just another brilliant detail. So, that's one lap up to the back straight. Here we go, WOT, not a care in the world. By the end of the straight the car was going 300kph. Those small S winders are tricky with a serial torque murderer, so I had to take extra care. I am usually very risky in these, braking as late as possible and as little as possible. The slight rear bias gave the car enough "turn" left to be able to take them at around 250. I was very impressed. I did however, almost go off course. Obviously. But I managed not to, somehow. Last turns, taken with the same risk, weren't looking at all like a bad day at the office. That's one lap of the Green Hell in 530hp.

It immediately and constantly reminded me of the 300ZX I love so much. That corner exit oversteer... That turn-in ability... The great gearing... Damn. What else can I say?
 
Honda Civic VTi-R

So, this is the first FWD car I tune in GT5, because I'm just not much of a front-drive guy. Even though I drive one in real life. Anyway, onto the actual drive. Stock, this car isn't much on a fast paced track. In corners, it's brilliant. And the car comes with Comfort Softs. So after one lap of Fuji to get reacquainted (it was my starter car), the car went through Extreme Makeover, the tuning shop.

Ok, did I read that right? 888kg? That's a really light car. With 276hp. Kind of like the Japanese gentleman's agreement on HP figures. Anyway...

The car revs to 9000rpm! That's 458 Italia territory! Launching from a stand still is also really fun. This, I did with TC on 1. The car makes little effort to take that needle all the way up to 9000rpm, leaving the TC working half-time. Gearing? Nothing wrong with it if you're not cornering in 2nd gear. Top speed sits at 260kph, just enough for the back straight.

Now, onto the corners. Being that I have no idea what a good FWD tune is, I just plugged in the numbers and off I went to the Nurburgring. Tuner Comments was drop dead serious. The car seems to be on rails with this insane amount of precision it has. Point to where you want to go and it will go there. Except when the required corner speed was exceeded. There, it's up to physics to take you where it wants to.

However, there seems to be an actual limit where the car will just refuse to change direction. It seems to happen (obviously) under braking, but it also happens at seemingly random times, when you least expect it and most need it. So I said hi to the barrier a couple of times. I guess this can be slightly corrected by sending the outside rear tire into the grass to induce oversteer. Gently slide, steer to the intended direction of travel, and after some little maneuvers the car is back on track.

One thing I really enjoyed when I was driving around was the fact that the car can use rumble strips (given they are not flat) rumble strips as a barrier of sorts to prevent it from going off track. And, despite the car being so able in corners, cornering speed was noticeably lower (around 5 to 10kph) than other cars, and this was with enough braking and on-time turn-in. But the car has acceleration able to compensate with that. Also, when the car lost all control and started spinning wildly, stepping on the brakes usually allowed a crashless stop. Why I'm telling you this, I don't know, but it's nice.

Overall the car is excellent when driven at or below it's limit, but otherwise you're just driving an 888kg weapon.
 
Welcome to the GTP URKMTC Battle! This tuning battle is to pay respect to the late SCC (Sport Compact Car) magazine which introduced me to GTPlanet about ten years ago. I have put together a few tests in which to put the RKM tuned beasts to the test.

I have compiled a few tests together to test the cars at their limit and beyond. The first two courses have been completed which will test things like lap times, over/understeer, acceleration, ride quality and budget. Each test awards the winning car 100 points while giving a big fat 0 to the losing car. Along with these test I have included a finale worth 50 points that will remain a secret until I finish the URKMTC Battle.

Let us begin with test 1 - this test deals with base prices of cars. First of all, I don't know how many millionaires are reading this but I am a regular Joe and simply can't afford just to buy a car and tune it up from the get go. I need time, and more money then I am currently making to even begin to start tuning my own car. RKM Motorsports was kind enough to lend out 8 cars to me to see which car will perform the best for its buck. Now these tuned cars will cost you quite a fortune to buy direct from RKM, so I am just testing the initial investment for a stock car from the dealership.

Here are the results -
1 - Mazda MX-5 @ $19,000
2 - Nissan Silvia S15 @ $25,600
3 - Mazda RX-8 @ $28,980
4 - Honda S2000 @ $37,800
5 - Nissan 300zx @ $39,500
6 - Nissan R32 GTR @ $52,900
7 - Honda NSX-R @ $119,570
8 - Ferrari F430 Scuderia @ $302,500

This leads to an interesting start for a great battle.

Points total :
Mx5 - 100points
S15 - 87.5points
RX8 - 75points
S2k - 67.5points
300zx - 50points
R32 - 37.5points
Nsx - 25points
F430 - 0points

Test 2 - Horsepower shoot out

How could we challenge cars before we at least get some baseline where their power is. RKM was kind enough to allow us to use their Dyno Facilities so wecould baseline their bHP to get a feeling for how much oomph these cars can put down. Just looking at the field, some of the naturally aspirated cars might have some trouble keeping up with the forces induction group. At one point I thought the F430 was so strung out that the engine might pop. A big surprise in this category is that 2 out of the top 3 cars were from the same manufacture.

We started by strapping the Ferrari onto the dyno. At first we heard the exhaust tone and realized this was not a normal F430. We were impressed by its 584hp at 8800 rpm, but it was lacking in the torque department with only 392 ft-lbs. At 5800rpm. It turned out a very linear HP curve while the torque fizzled away not very abrutly either.

Next the engineers from Mazdaspeed were on hand to get test results of what RKM has done with one of their factory cars that was given to RKM in order to get specs and results. They were looking to utilize all the data so they can apply it to their factory supported effort in the Grand Am and other touring car efforts. The RX-8 pushed out an amazing 406 HP at a wailing 9300 rpm and a not too shabby 266 ft-lbs. At 6300 rpm. These are pretty good results for a rotary engine. You don't see that power coming out of these engines with the longevity RKM claims to have with rotary powered cars.

On to one of the pinnacles of the 1990s with the Nismo 300zx. This car has been known to put out loads of power while its only archilles heel is trying to keep temps down in the crammed engine bay. We were expecting this car to really impress our panel of judges and it did not let us down. It pounded out 577hp at 6000 rpm while producing 576 ft-lbs at 4800 rpm. If power delivery is what you need then look no further then this Monster!

Back in the late 1980s a team of engineers was looking to put together a supercars that could keep pace if not surpass the Europeans in this class of cars. No one up until this point was ever able to achieve this until Honda rolled out the NSX. We have a '02 model here which has the looks to kill. What did it produce. A very respectable 401hp at 7700 rpm and 298 ft-lbs at 6200 rpm. The sticker attached to the car should say 'Got RKM Inside Yo'

Pulling up next was another product that the Mazdaspeed engineers were looking to gain data from. There was no crazy LS1 swap put into this car. Everyone knew that this MX5 would also not top the charts with its power. The MX5 put out 246hp at 7400 rpm and 202 ft-lbs at 5400 rpm.

Here is a car that I had many vivid dreams about, but realized living in the U.S. I would never get the chance to own. The Silvia S15. Many 240sx have been tuned and modified to become the JDM Silvia in the S13 and S14 forms. RKM had this one special car delivered straight from Japan while spotting it online. The car had not been driven more then 150 km. After getting the all important RKM treatment my little dream car pushed out 428hp at 7300 rpm and a lovely 338 ft-lbs at 5700 rpm.

With the next competitor stepping up to the plate, I had a slight memory of almost having my hands on this car. A pregnancy occurred and I witnessed the car slip through my fingers. This is a shiny example from 2006; the Honda S2000. Laying down 323hp at 8700 rpm and 205 ft-lbs at 7200 rpm.

Our last competitor is not shy at all when it comes to dynos. A sought after model of Godzilla is what we have here. The R32 GTR made its appearance and changed the tuning scene forever. Even with later models emerging with the 33 and 34, they could not capture the raw feeling the 32 posssessed. Godzilla put down a respectable 417hp at 7200 rpm and 356 ft-lbs at 5200 rpm.

One more test to go before we get to really start showing off what these beast are really capable of.

Points total :

S15 - 162.5 points
300zx - 137.5 points
RX8 - 125 points
Mx5 - 100 points
R32 - 100 points
F430 - 100 points
S2K - 87.5 points
NSX - 62.5 points

Nissan and Mazda seem to have jumped ahead in the points standings while Ferrari and Honda are waiting for a chance to get out onto a track and start to score some points. Now that all the bench racing is done we will proceed to the Ride Quality test. This test will be performed by Mrs. Axle and we will hear the results directly from her. She is no stranger to racing. Before we had our little daughter date night wasn't movies or going to bars. We spent our dates grinding it out against each other on the go kart tracks.

Along with the ride quality test, our oversteer and understeer test results will get shown along with lap times at Grand Valley Speedway. Coming later is still our surprise round and a few more performance contests we put the cars through the paces. There are some interesting developments that come once these cars get on the track. I would post them now, but bed is calling and I can't show everything right now. We need our cliffhanger to start right here :-)
