RKM Motorsport - Tuned Tuners - May '13

[VTiRoj]

Your Hondas always turn out amazing, I'm looking forward to seeing what you guys do with the S2000

Why thank you. I intend to tune all the road-going Honda's in the new dealership, so I should have an S2000 out at some point.

Hello,

I have seen the tune for the NSX-R, and I wonder if it could work on the NSX GT500 Stealth Edition, I don't know anything about tune, so perhaps it is stupid to think so.
Thanks in advance!!!

The NSX-R tune is a bit soft for the GT500 and the GT500 has alot more downforce than what's available on the NSX-R. The settings may not transfer that nicely. That said, I do have a Stealth NSX GT500 myself so if I ever get round to driving it properly, I'll post some settings up.

 

[Matauco]

Thank you very much!

I'll be waiting.

I did some online in the 787B and it felt quite weirdly different from Single Player, car seems to be less stable on Monza. Could be just my driving though...

Online has tyre wear and temperatures on. What you're noticing is the difference between warm tyres and cold tyres.

 

[Kyaw]

Yeah probably.

 

[Rotary Junkie]

Let me start by saying I need to wear a condom when I drive this car. Ok all joking aside this car is a beast I loved it when I first bought it but knew it had way more then I was getting out of it. True story I sent this vehicle over to get tuned elsewhere and wasnt thrilled with the results(It was ok but I felt it could have more) I sent to RJ and I am not disappointed. He kept it easy to handle and fast as hell. I did have to set the AYC down a little bit only b/c of the way I drive it was overtaking my turning lol. The car looks feels sounds great and will not disappoint I promise. RJ keep up the awesome work and I will keep you with project cars lol

👍 Very glad you like it.

I have tested the Scuderia, and it is amazing how a good tune could change a car, now I am tuning the Z06. I don't know what people like me (without any idea about tuning) would do without your help.

Thanks in advance!!!

As Roj said, the GT500 NSX is quite a bit different to the road version. In fact, the suspension geometries are vastly different, the engine points north/south instead of east/west, and it's got massively higher downforce. The settings needed are vastly different.

Sorry for being a bit lazy about getting around to writing this review for the Ferrari Scud, but here it is.

At first, I wasn't sure what to make of this setup; the negative toe in the rear had me raising my eyebrows and the car felt a bit awkward. Well... that was all on me, I had to tell myself "hey doofus, stop driving it like a Subaru, that engine is BEHIND you." I started my lines further out, braking a bit earlier and rolling into the apexes sooner. Once I started treating her properly, she set her line and holy ****, put your right foot on that firewall and prepare to rocket out of the corner like a madman on a coke binge. LOL. The exit velocities on this car are extreme. Master your apex points and throttle control, and this machine awards you in spades.

Summed up: drive it properly, and it eats corners for breakfast. Well done once more RJ, I approve heartily.

 

[ChadSteeler]

Ferrari Race Car is a big win RJ been working all weekend but I will post a review soon, I just didn't know is if I post it before you release the set up let me know please. thanks again

That setup is going to be a bit like the CLK55 AMG I did for kennygt14; as in it won't be posted. Would definitely like a review on it anyway (preferably here) just to see how it feels for you though.

On that note, review for a 240SX tune that RJ provided to me a few days ago.

388HP, 1088kg
Now the 240SX is my favourite car, however the rear was sliding way too much under heavy braking and acceleration when running the stock tune. So I slapped everything onto it and sent it to RJ. He gave it back with a few notes.

-He swapped it to a mid range turbo for a nicer powerband
-It still slid on exit

With that in mind, I took it out to the Ring for some runs. First thing I noticed was the sliding out of corners, as RJ had warned me about. The next thing I noticed was the severe understeer at high speeds. RJ later explained both of these were unavoidable due to the lack of downforce available on the car. That aside, the car turned nicely and it was good out of the corners, despite the sliding. I did have some problems with jumping and high speed curbs, but that was mostly due to my errors. I ran an initial 7:47 and improved it to a 7:42. (Note that I am a below average DS3 user and made 2 major mistakes on my 7:42 run) On technical courses, the sliding is a slightly bigger problem, but the understeer problem is eliminated.

It was still a blast to drive, even with it's faults. The sliding was quite enjoyable and I found it was rather easy to handle. This led to some spur of the moment drifting (as seen by the picture when I later went to Eiger Nordwand Short Track). While it may not be the fastest ~400HP Japanese car out there, it certainly still has a place in my books.

Performance - 8/10 (had to knock a few off, even if it's out of your control)
Enjoyability - 10/10 (biased since I love this car)

So no FC trany for the Gallardo?

Nope.

 

[Cory Gillmore]

The Lexus LFA GT: Man am I disappointed with this car. Your setup really does wonders for it but it still is a heaping pile of you know what. Without any downforce to speak of, this car is severely limited in it's handling capabilities. For a car that looks so amazing and costs so much, I just wish it was better. Kinda pisses me off that PD decided to not allow us to put aero parts on it. Could it be that Lexus didn't allow them to? This car was released in a recent DLC pack for Forza 3 but I haven't driven it yet and probably won't cause after playing GT5, Forza 3 just looks and feels horrible to me. I would like to know if F3 allows aero parts on this car though...

 

[Asane]

Hey, you planning on doing a tuning for the AE-86 Shigeno Trueno?

 

[jjohan35]

I really don't understand your tuning for the Civic 08. FF cars tend to understeer already (particularly the Civic- I own it in the game and in real life), but your stiffer front spring rates and stiffer front dampers all promote more understeering. The only thing you guys had in the tuning that somewhat decreased understeering was the stiffer rear anti-roll but it wasn't enough. When I tried your tuning on my maxed out Civic Type R 08, I felt it understeered way too much. Was there a typo in the numbers?

Let me guess... Maxed includes racing soft tires?

 

[jjohan35]

Racing tires soft, medium, and hard. I went bananas on the Civic because I own one in real life. I also feel that the really low spring rates in your setup make the car feel really boggy. Most Civic tuners in real life (myself included) tend to stiffen the spring rates to make the car a bit more snappy on the tracks.

 

[Turbonutter]

Nevermind, I'll be nice.

 

[jjohan35]

I just bought the recommended sports soft tires from your tuning. No dice. Still boggy, still understeering.

Why not try it with the tires we built it for and compare it to default with those same tires? 💡

Edit:

Hey guys, why aren't racing slicks helping my times with my 2CV?!?

Perhaps it doesn't have the power to need them.

Define boggy. Then try default settings. Then try to make it actually corner faster than it does on the same tires.

 

[jjohan35]

Boggy: car feels heavy and unresponsive. For most tuning in real-life automotive racing, ways to fix this include stiffening spring rates, stiffening anti-roll, or increasing tire pressure. I don't know where you guys are pulling your numbers.

The entire setup understeers mid-corner and corner-exit. I made front spring rates less stiff compared to the rear, increased spring rates for both front and rear, and inverted the rear/front damper settings to reduce understeering and promote some oversteering. It's basics in automotive tuning.

Out of our arses based purely on feel and lap time.

But did it work? I want lap times.

I personally was very disappointed when I did my first FWD tune in GT5 and found out that the same things that worked in GT4 work here for FWD cars, albeit to a lesser extent. "Real life" tuning goes completely out of the window at a certain point in this game, particularly with FWD cars.

 

[jjohan35]

Sorry but your tunings aren't end-all, be-all. My lap times improved after I made the modifications on 6 different tracks. It was an honest question about whether it was a typo or not. And so I started wondering where you were getting your numbers from. There's no reason to be 'smart' about it. Maybe it's purely dependent on driving style. If you guys don't allow discussion or leave any room for improvement, then what's the point of wanting reviews in your offer?

There's really no point for me to argue with a 17 year old. Good luck with your online tuning.

This is something I'm also interested in. Do you guys purely base your tunes on getting the fastest lap in the game, or from a feel perspective of a properly simulated tuned car?

I've posted on this thread previously saying I experience a lot of understeer with the RX-7, and you mentioned that the car was made for turning under brakes. The feel for me on that car is just completely wrong. Yeah I can get faster lap times if I turn under braking like you suggested, but that is something I would never do in real life on a FR car. Not only is it dangerous if you misjudge a corner with the late braking, it's also the quickest way to shred tyres. As there are a lot of positive feedback on the RX-7, I kept thinking to myself whether I'm totally wrong regarding my opinions on the car. But I've tried a few other cars from your list since then, and I get quite a similar feel to a lot of them (in which I experience a lot of understeer). Now jjohan35 is the first other person to say it so I'm interested in your response to him. Personally I enjoy the simulator side of the game so I tend to prefer tune values that make sense to me as it would do to a real life car, but I understand that other people may only care about laptimes.

I just think it would be nice for tuners to describe their tunes rather than putting out values for the crowd to blindly follow. If you describe each value and why you changed it, what affect it has on the car etc, the thought process that goes into a tune, the adjustments order etc, sure it might take longer, but that way everybody learns.

 

[Rotary Junkie]

@jjohan:

Well played on dragging age into it. Well played.

That said, I'd like further information as to what settings you wound up using, as well as a bit of insight into your driving style, as I've consistently found that having stiff front springs coupled with soft rear springs and the reverse on anti-roll bars to quell understeer better in FWD vehicles on-throttle. Roj's '08 Civic setup is close but a bit conservative (I'd have gone about 50% stiffer on the front springs with less anti-roll in the front and more in the rear) and I can see that it may have the understeer you speak of. My apologies for my actions earlier, I wasn't exactly in the world's greatest state of mind.

@Corthalis:

Regarding tire shredding, safety, etc... It depends on the slip angle being used. There is a difference between the car rotating slightly on entry and the car losing grip/sliding. The former is what I refer to rather than the latter.

As for tuning for laptime over realism... Yes and no. I tune the car specifically to feel good to me and therefore go as quickly as I can make it. There is genuinely a difference between that and making the car the absolute theoretical fastest it can be. If that were the case, the cars would be borderline undriveable for anyone but the very best. From my experience in the PC sim world (~1.5 years, very little) the setups the "aliens" used were EXTREMELY loose on entry and neutral-to-loose on exit. Was it fast? Yes, if you got it right. Was it safe? If you had the skill to keep it in check, plenty. Could those less skilled use it at all without going out in a gigantic virtual fireball? No.

And for the "explain each setting in detail" bit... It would be extremely helpful to those willing to learn and I plan to do something to that effect within the near future, but it's not something that can viably be done for every tune.

This is one of the reasons why the engine is stock. With no downforce, the car just becomes too insane for it's own good since it won't stick to the road. I completely agree with you. I tried to tame it without losing too much speed anyway. 👍 F3 probably has it's own universal splitter kit for every car. I don't know exactly, I've only played F1 and F2 at a friend's house.

Hey, you planning on doing a tuning for the AE-86 Shigeno Trueno?

It's planned but it's quite far down the list.

I really don't understand your tuning for the Civic 08. FF cars tend to understeer already (particularly the Civic- I own it in the game and in real life), but your stiffer front spring rates and stiffer front dampers all promote more understeering.

When I tried your tuning on my maxed out Civic Type R 08, I felt it understeered way too much. Was there a typo in the numbers?

First off, I'm disregarding the little arguement with RJ just now so we can keep it civil. I own a Civic too! Hi! Anyway, I understand where you're coming from. On paper, the settings look understeery and pretty much backwards. But in GT5, they work. This tune works for me and quite a few other people who've tried it. I can only guess that our driving styles differ quite alot when it comes to FWD cars. There's no typos although I will go through the settings again just to make double sure.

This is something I'm also interested in. Do you guys purely base your tunes on getting the fastest lap in the game, or from a feel perspective of a properly simulated tuned car?

I tune based on feeling rather than laptimes. I'm not a record breaking driver so tuning time attack cars would be pointless for me, as I'd have no chance to test the car properly. Most of my tunes are just intended to be faster than the original without making them crazy and out of control.

I've posted on this thread previously saying I experience a lot of understeer with the RX-7, and you mentioned that the car was made for turning under brakes. The feel for me on that car is just completely wrong. Yeah I can get faster lap times if I turn under braking like you suggested, but that is something I would never do in real life on a FR car.

Personally I enjoy the simulator side of the game so I tend to prefer tune values that make sense to me as it would do to a real life car, but I understand that other people may only care about laptimes.

I don't think any of my settings make sense as real life settings, but they make sense within GT5's world, which is where these tunes are driven. I realise there's a huge driving style difference when you treat the game realistically vs treating the game as a game, hence why alot of our tunes may feel understeery, because we treat the game as a game.

I just think it would be nice for tuners to describe their tunes rather than putting out values for the crowd to blindly follow. If you describe each value and why you changed it, what affect it has on the car etc, the thought process that goes into a tune, the adjustments order etc, sure it might take longer, but that way everybody learns.

It would be nice and everyone would learn from it, but it would be like writing a diary for each and every car. It wouldn't just take longer, it would take longer than tuning the actual car, which I don't have the free time for. Sorry.

We don't mind if you guys change our settings. If you find a different value suits you better, go ahead. We're just two people running a tuning shop in our spare time, we don't have the driving styles of the millions of GT5 players, so naturally our settings wont work for everyone. 👍

 

[joxdj]

I used your R34 Settings as a base to help me with my R32 and man does it handle like a dream now. I have it set for under 300hp races and i dont think anything can touch it that weighs over 1000kg heh.

Edit: Oh yah i tried the Civic type R and your right, if it was not for the spoiler... WHAT A SLEEPER!!! hah. I didn't expect that thing to be so fast even tho it does have quite a bit of HP its still a civic. It was within a couple seconds of my other 400hp cars on SSR5 which i did not see coming. Not really a FWD guy but this little car makes me think twice.

One more question,
I know this is broad and will be different depending on the car but is there an average power threshold when slicks are actually needed over sport tires?

Tuner Comments:
As the spiritual successor to the old “Black Beauty” 787B from GT4, this Stealth model has inherited the title and does the name justice. This Black Beauty tune turns the 787B into an easy to drive, race-winning machine. There may be faster settings out there, but none are this easy to drive whilst keeping the 787B’s speed higher than it’s opposition. After serving me well since the start of my GT5 career, I decided to send the settings to Kyaw after he requested some 787B settings. After finding out it works well for him too, it prompted the public release of this beauty.

Hey, I bought the 787B from the Mazda dealership and all the parts you listed from the tuning were already installed, but I only have 768 hp..

Edit: oh, nvm what I said.

I listed them just incase the normal 787B doesn't have something the Stealth does. Also you'll gain some bhp from breaking in the engine as you drive it. 👍

Also, would you recommend getting the chassis reinforcement for the 787b?
