RKM Motorsport - Tuned Tuners - May '13

axle

Just to add to the CR-V review, I lowered the rear downforce to 15 and found it was a lot happier going from ugh speed into a tight corner. I think if it gets lowered a little more it would turn even better but at a lost of stability going into the corner.

I'll have to try this out once I get to tweaking the CR-Z again. 👍

need a power house amuse turbo s2000 tune in here!

There's a normal S2000 on it's way. The settings may work on the Amuse Turbo. 👍

Willing to provide you guys some cars for tunes. I'll just be duping them so no big deal. We need more tunes from you guys.

Here's a list of the cars I have. Not the best garage, but what can you do.

Ferrari Enzo '02
Lamborghini Gallardo LP 560-4 '08
Nissan 370Z Tuned Car (GT Academy Version) '08 in Chrome Paint

Well that's very kind of you! I don't want to take advantage too badly so I've just picked out 3 (in the quote above). Seeing as I'm in the UK, I'm not sure if I can even recieve the 370Z, since I can't obtain it in-game myself. I just miss that thing from the TT demo.

Thanks alot!

Went for Rotary Junkie's tune of the LP560-4 and am a very satisfied customer breezed the Gallardo event, went for a little more weight reduction and a different wing but very impressed with the results. The car feels very intuitive but not over-responsive and I like it how the nose dives under heavy breaking Not braking in a straight line does sometimes cause the back to skip out a bit but nothing too serious - I read it's a problem with the Murcielago too? Thanks for the time and effort on your part! 👍

RUF CTR "Yellow Bird" '87
RUF RGT '00
Mercury Cougar XR-7 '67

Reduced the list to the three I'd be most interested in... I hope the Cougar doesn't disappoint me like the GT350 did but I've got a suspicion it may.

Edit: @Goffin: Good to hear it worked out; honestly a stock Gallardo can breeze the Gallardo event but this thing as it is will do the GTWC on sports tires so...

That M5 tune is so much fun to drive. Also loved the RX-7 and Z06 RM tune also.

@Rotary Junkie

I maxed out a Mercury Cougar XR-7 '67 at the beginning of my A-spec career. It was a huge disappointment, but the GT350 is still one of my biggest disappointments so far too!

Aye, the GT350 isn't actually a bad handling car with the right setup but then it is. What I mean by this is while it feels well balanced, it seems to have the grip of a tire level lower than equipped (S3s feel like C3s, R3s feel like S3s). The Cougar was much the same way in GT4 but not quite to the same extent.

And thats why it`s not worth to struggle and waste time with that car from my perspective. Especially with plenty of superior alternatives!

The GT350 is like a ice cube on a frozen lake... touch the steering wheel while braking - you are dead, touch the throttle while steering - you are dead!

It has no mid engine, it weights only 1055kg and is still garbage with racing soft slicks!
Somehow this car feels bugged, although most of us bought this legendary car immediately when it showed up at used car dealership it`s not worth to drive! Sad but true...

Oh yes, Volvo C30 👍

370 looks neat aswell and that colour green looks great.

Styling rights on the 370GT go to NTwo (you may or may not have seen a review of Roj's NSX-R by him earlier in the thread). The color is Sub-Lime (written as Sublime) off the 1970 Challenger.

The C30 is the absolute quickest FWD I've tuned as yet and I've got my doubts as to whether it can be topped without a DC5 RM, and perhaps even that may be slower.

Damn, I don't have that colour. Might have to buy the Challenger just to get it!!!!

I love the C30, if I could afford it I'd buy one (in real life!!). Either that or a Citroën DS3, which I'm very disappointed isn't in the game.

Hello,

I think the Volvo weight is wrong, I am applaying your settings and I have 1196 Kg but perhaps it is my fault.

Thank you!

Oops! That's my fault; it should be 1196.

Thanks for pointing this out, fixed now.

Just doing the RX-7 to take part in the Seasonal Event. Does it need Rigidity Improvement? It isn't mentioned in your post but I always put it on my cars to improve the handling?

Also, no exhaust?

If it's not listed, I didn't use it. It will either help the car or cripple it, no idea which. Would recommend not using it.

Did you seriously get that much power from the Skyline 370GT with just those mods? I tuned a Skyline Sedan today and before run-in only had 455hp with EVERYTHING. I then ended up using a Sports Exhaust for sound which gave 434hp. There's no forced induction available for it though. I also regret to report that just like the Evo X's weaving on straights bug, the Skyline Sedan premium model's bug from Prologue is still there too, in that the steering is completely dead off-centre. You have to turn the wheel a fair ways before anything happens. This is with 900-degree steering though.

Yep. Apparently it only makes another 30-40hp from being fully modded though.

Also, the EvoX's "weaving" isn't entirely a bug, it's the active yaw control being a bit hypersensitive, yes, but it's got a very valid explanation.

Edit: @GavBlade: Nope, not for the power specs listed.

Excellent work on the 370GT! I've had one sitting in my garage waiting for a solid tune. Any chance you guys might consider working your magic on the '06 Infiniti G35 Coupe anytime in the future? I haven't noticed any tunes for that car yet, surprisingly. Once again, nice work.

The suspension for the rear of the 370 says -125

Will switching the brake balance round make any significant difference?

The G37 should share enough that the G35 coupe ought to work the same. That said, I get the feeling you haven't even driven it as you didn't point out the typo

Whoops again. I hate screwing up releases. Should be fixed now.

As for the brakes... How do you mean?

You mean with the ride height? I caught it but just assumed off the bat that you meant -25/-25. I'll plug this tune into the G35 too and see how it works.

Switching the brake bias so that its 9 at the front and 5 at the rear instead of 5 at the front and 9 at the rear. Isn't the rear more likely to kick out if the brake bias is more to the rear?

What I know about all this tuning lark could be written on the back of a stamp so you'll have to excuse me!!

Yes, the rear is more likely to "kick out" with high rear bias settings... But with ABS on 1, I've found that there is fairly rarely too much rear brake pressure and somewhat often a bit too much front brake pressure (or close to the most that can be safely run). The 5/9 setting helps immeasurably with turn-in so long as ABS is on (with it off, I find that a heavier front bias is much more controllable for fairly obvious reasons).

Rotary Junkie and Rog.........You have a gift waiting for you. We (everyone) appreciate your work.

Thank you very much! It's like my birthday came early this year.

Gonna try this setup on an OPERA PERFORMANCE 350Z '04

Long time no see guys!

Have you guys got any plans on tuning the Peugeot 908 HDI?

I'm gonna be using it for this Le Mans championship and i want the car to be more responsive. Next track is Suzuka and i dont think the 908 is nimble enough to handle all them corners.

I can gift you the car if you can sent it back before this weekend.

As requested by Rotary Junkie I've decided to pit Avid vs RKM in regards to the Nissan Skyline Coupe 370GT Type SP '07.
Both cars were tested with Sports: Soft Tires as well as a Top Speed of 180mph.
Side by side comparison here: https://www.gtplanet.net/forum/showthread.php?t=159188#post4539859

Test Track: Laguna Seca
Best Lap: 1:32.464

Corner Entry: Good turn in, but unfortunately this car doesn't want to stop. Thinking about it, this is probably because of the tires and I'm so use to using Racing Softs universally. The higher brake balance here helped a little bit, but the car is still very resistant to rotation when on the brakes.

Center of the turn is an upgrade from Avid's tune as written, but still lacks the amount of turn I enjoy. I'm almost inclined to say the only reason the center is better, is because the entry gave me a better angle, so I feel the center is still suffering from understeer.

Corner exit: More understeer. Getting on the gas too soon forces the car to the grass. Put too much into the wheel and try to throttle the car out of the turn and you'll see the back end snap enough to get you out of wack, and send you all the way around if done so without concern.

Overall, the car was consistent and a bit faster in it's written form than the Avid Tune. In the 5 lap stretch I ran 2 .4's and 2 .6's. The car feels sluggish in acceleration, braking as well as handling properties.
