Hope so, the Volvo C30 takes an age to change from 5th to 6th gear (i use auto gearbox )

If you MUST stick with auto gearbox, switch to the high-RPM turbo. The C30RS needs to be shifted at about 6000rpm instead of redline for peak acceleration; this isn't going to change by fully adjustable gearing (though the rate of acceleration will be much, much quicker).

Quick question for you guys if you don't mind, to save me starting a new thread.

I've got a McLaren SLR thats tuned (and of course has had the suspension and everything adjusted), it hasn't got any aero on it though, if I was to add it, would I need to adjust the suspension?

It may want some tweaking to make it looser at high speeds to take full advantage of the downforce but if it's already a bit on the loose side it should be fine.

VOLVO C30RS – R35 WUT REVIEW
Reviewed using sixaxis controller on Region 4 PS3, update 1.05.

Parts only (default settings)
Lot of pitch under brakes. Bucketloads of it! At first, I thought the car was stubborn to change direction, but actually it just takes a while for the front to build grip- the mid-corner balance is actually very good.

A lot of entry understeer (and with all that dive, it’s hard to tell if it’s due to weight transfer or brake bias), so I was braking early and trying to get back on the throttle before the apex, which is very unusual for a fwd car. Luckily, the exit grip is excellent, the front tyres are doing an excellent job to meet both the engine’s and the steering’s demands.

Gearing is far to short, as is to be expected with $50k + worth of mods under the bonnet. Front grip at high speed is excellent. Being a fwd with great front grip under power, this car has potential for greatness if RKM can sort out the corner entry problems. Suzuka lap time 2:21.7.

RKM settings
Note: Although the tune has the top speed set to 205 km/h, I was already hitting the limiter with the default setting of 230 km/h (actual top speed was much less), so this review has been done with top speed set at 250 km/h.

Much less dive under brakes, phew! Entry understeer is still present, but far more controllable you’re not staring at the ground in front of you. It does feel like there is a bit more mid-corner understeer than the default settings. Perhaps this is an unavoidable side-effect of curing the dive problem (the spring settings are a tad... errr... unconventional!).

Nicely chuckable without ever feeling like it will bite back. Also, front-end precision under power is even better than the default setting, which I didn’t think was possible! Suzuka lap time 2:20.0.

 

[Rotary Junkie]

Top speed should be set to 205 mph. Neither of us ever use km/h for gearing measurements; though such confusions are why we still bother to list the actual gear ratios. (Them not matching = either you've got the autoset wrong or the wrong parts on the car)

Also of note is that it needs to be shifted at 6000-6250rpm to extract the most from the mid-range turbo.

Aside from that, not much to say you're "wrong" about; I may be revising the car soon when I go to fix the ratios after the update, I think I can get a bit more understeer tuned out of it. Thanks very much for the review sir. 👍

VOLVO C30RS – R35 WUT REVIEW
Reviewed using sixaxis controller on Region 4 PS3, update 1.05.

Could the understeer be due to the power levels..?? I experienced next to no understeer, certainly compared to similar cars ('06 Focus ST anyone??). However, I've been running this creature sub 355bhp (stock turbo vs mid-range), so substantially down on the listed 420bhp. I've found this car delivers smooth power and the grip seems to go on forever. It only lets go when I do something daft (which on race day, can happen a lot!!). I'll be doing a head-to-head comparison with this and two other cars shortly. Built within our own restrictions, but with RKM setups, we'll be trying to push all three around Trial Mountain in sub 1:34s. Results Thurs or Sat, depending on which night we can all make it...

<Cy>

PS - I'll admit, I'm a little in love with this car. I haven't raced it to the full RKM specification yet, so that may change ... but I doubt it..!!

 

[kennygt14]

Nice playing with you RJ i tried to use most of your tunes, but i modified most of them for 450 and under ill probably build some more cars under 400hp the TVR was the only one under the rating good races though

 

[Iron-Thunder77]

I tried out your audi v8 '10 tune, and its great. It enters turns quickly, but doesnt go off the course. It accelerates to the front of the pack easily, and with a little tweaking, will make it perfect for my driving style. Nice job. 👍

If you wouldnt mind, I'm searching for a lotus evora '09 tune. The car itself will understeer at first, but then suddenly oversteer and spin out if you accelerate. Very tricky car indeed. Any chance you could help me out?

Honestly, I've driven that Volvo in a few different configurations from ~300hp to the full 420 on both S3s and R3s; less power makes it understeer "less" by way of reducing wheelspin but the entire point of the tune is to make it still exit corners quickly despite the inherent wheelspin; indeed, it is rough on front tires when being driven at max pace but it doesn't really understeer any more than 80% of "proper" sports cars as the nose tries to pull it around the corner.

Nice playing with you RJ i tried to use most of your tunes, but i modified most of them for 450 and under ill probably build some more cars under 400hp the TVR was the only one under the rating good races though

Aye, the same. Normally we do one of those rooms every couple nights; I found it odd how often you were spinning the TVR though I suffer more from understeer than throttle-oversteer.

Well, I hate to say it, but The Lion's Den Performance beat us to building an Evora... I've got one semi-tuned for online (it works but isn't as fast as I know it should be); I'll likely bother to finish it properly after the next update; the power delivery is just wrong for use in power-cap rooms without resetting the gearbox for each and every track you go to; this will be avoidable once I can set the ratios myself.

Bought another R34 from the dealership and tuned it with the RKM settings.

It seems like RKM motorsports has made a true supercar killer. I tested the tune in the F1 portion of the car's spiritual home, the Nurburgring. Something shocked me: the AI's were using bonafide supercars such as the Mclaren F1 and the Veyron to name a few. And as usual in an Arcade race, I start in the very back of a 16-car grid. Difficulty is at Professional.

The Skyline handled pretty well, despite not being driven the way it was intended to be. Yet driving with a few aids turned on still doesn't infect the car with AIDS. Only ABS and Traction Control at 1, the rest off. Also driven with automatic. I'm not really decent at driving, but at least I can tell you guys how your setup handled for me.

This R34 can also take some abuse. It sustained a bit of damage during the testing, yet it still handles fine. It's not the type of car that leaves you and makes you lonely even for a single dent. It pushes and pushes, no matter how injured it is. Even with all aids off, it may bite back, but not with a violent temper.

It's stable, just the way I like it. May not be good for drifting, but I'll have lots of fun doing time attacks in Eiger Nordwand. Driving it was also a learning experience. It taught me more on being easy with the brakes (I use a controller, I just re-mapped the controls).

Just five laps, and I dominated them even at lap 3, with a few mistakes

Verdict? It isn't really hard to drive. It's stability gives other supercars a hard time. Watch out if this is up on the corners.

The R34 is one of my favorite cars, by the way. I'm glad you guys made a setup for it. I would definitely be interested in a showdown between the RKM R34 and the Mine's R34.

I'll post later what will happen if you brought this car to the dirt/snow tracks. But of course, I need to soften the suspension settings because rough tracks are rough. 💡

 

[CaliforniaRacer]

Question for you RKM. I've been looking buying new either the Puegot 908 or the Mazda 787. I know both are unquestionably beastly, but which car do you prefer to get races done with? Odd question, i know, but i was hoping you could shed some light over here.

You're welcome! Sorry about the mph screw-up, yeah I didn't check the ratios cos until PD fix the FC gearbox *cough*, they don't really mean anything.

The exit traction and composure is even more impressive, considering I was running shorter ratios than specified.

Thanks for the review! Yeah the R34 is pretty sweet. You can turn the TCS off and still enjoy total traction. Glad you found it good to drive and well done for spanking the supercars with it.

As for the Mine's R34, it won't survive.

Soften the spring rates and dampers and raise the ride height up, it should be sweet off road. 👍

There's no A or B spec race that the 787B can't win. Mine is a Stealth so I prefer it over the 908 because it's really really cheap to refresh the chassis and rebuild the engine. If it was the normal 787B with the steep price, I'd sway towards the 908 because it's a lot faster on the bigger curcuits.

It drives brilliantly for me Kyle. It may even be the poster's driving style that made it seem to understeer (I'm constantly staggered at how differently some of these cars drive). You do need to get rid of a bit more speed when entering a corner, than you would with a RWD. But then you don't really have the opportunity to power oversteer. FWD relies more on lift-off to provoke the same sort of tail action. And frankly, your setup finds so much grip coming out of corners that I can't find fault. I've driven FWD cars my entire life. I live in England, so there's little point in buying a RWD car, IMO. And certainly no point getting a cabriolet..!!

Keep your eyes pealed for a three-way Hot Hatch Battle Report on Saturday morning. My mates and I are off to Trial Mountain, to see if the "Ugly Baby" can really keep up with the C30RS and its ST bretheren

can you tune my aston martin db9 coupe (the premium one)

For all you RKM fans that haven't noticed there is an interesting interview with the tuners in the GTlife magazine.

It was great to have a feature in the first issue. Very sweet job on it by the way, still haven't read all of it. It's really like a magazine.

 

[uMadson?]

Hey, you guys need an R33 to tune? I may help you guys out by donating one of my not-decently-tuned Wangan monsters. Every bit of this beast is upgraded, it currently has 683 horsepower and can run 360 km/h or faster. With these upgrades, all you have to do is to tinker with the settings.

Here are pics:

If you guys need it, I'll send it to you when I'm able to get my hands on the controller again. And you're free to re-paint it, as long as it's yellow or orange.

 

[Rotary Junkie]

I'll probably release an R33 eventually.. I don't know when "eventually" is though, sadly, as I've not made myself entirely happy with it yet...

For reference, I have two premium R33s and one or two V-Spec LM Limiteds in my possession; that is one hot color scheme though.

[GavBlade]

Would the RX7 R400 take more power?

I've just noticed I've got one but its tuned to the max at the minute (544BHP)

 

[Rotary Junkie]

It can indeed take max power...

But it can also be detuned to the correct specs from a max-tune car.

 

[GavBlade]

That's ok then, although I have detuned it anyway by removing the turbo and changing the exhaust to a sports one.

What's the reason for not lowering the car?

 

[pHLo]

and i was wondering why you didn't install the carbon driveshaft....

Haven't found a way to make it handle the way I want with it lowered mainly.

and i was wondering why you didn't install the carbon driveshaft....

Oops! Keep meaning to fix that, haven't gotten around to it yet.

 

[VTiRoj]

Oops! Keep meaning to fix that, haven't gotten around to it yet.

It's like me with my M3's in GT4.

I've managed to set fully adjusted gear ratios for the March Super Turbo and Civic Type R now. They're schweeeeeeet.

Nice one, will do the March later but my Civic Type R is using the settings from your race modified Civic, and I think it has a different horsepower to both of them so I think I might just leave the gears on that one!!

Just finished updating and noticed that gear ratios are customisable as well as weight ballast settings and power limiter settings. Just wondering when you guys were planning on updating your tunes.
