I wanted to complete that tuning car championshio in Proffesional hall, and i used my '99 R34 Skyline, used, which was already tuned to around 500hp, now i put Turbo 4, best Exhaust, that second suspension,(not full), put some good brakes, and it was UNdriveble!! It would slide out from turns by it self, i thougth i was pressing the gas pedal too much, but that's not the case, it really is uncontrolable... I even put spoiler for downforce, and didn't change a thing..
Then i thought maybe it's justa that version of car bad, then i bought a brand new '02 R34 Skyline M-spec(not sure if this is correct), Nurb edition, and i tuned it the same way, to around ~700 hp, and again it slided like crazy, not driveble at all!! I didn't change the tires, i leaved it with Sport medium..
So... what am i doing wrong here, i thought that Skylines are stability kings :sly: :)
Any help appreciated...

I'm by no means an expert, but what kind of tyres are you using?

Sports medium, i've said that in first post, u must have missed it.. ;)
I didn't try with some better tires, because i am use to this tires, and i see people say N1, N2 tires are for simulation, but i find driving with them too hard, it's not like that in real life, i mean M3 CSL surelly doesn't have that bad tires(N1, N2) in real life....
So... are u saing that i have to switch to Racing tires, when my car is heavilly tuned??
 
the skyline can handle alot of power. 700 is perfectly within range. you problem is a combination of a few things. one is the tires. sports cant handle 700 hp, but you dont need to change your tires. Fiddle with the front to rear torque distribution. Try putting 25 percent or less of the power to the front. your overwhelming your front tires so sending power to the rear should take the car from terminal understeer, to a tail happy brute thats easy to controll. Further more, add a set of racing tires on top of that tweak and it will become a monster. (skyline fans would say "Godzilla". Thats a good thing by the way.)

Ok, i'll try that, thanks....
 
vcd tuning doesnt do anything for me. i have a 423hp Skyline that is tuned to have some decent amount of oversteer. I wasnt really trying to drift tune, just looking for a good turn in and none of that nasty understeer but it is very easy to drift.

Its a work in progress but thats what i've got sofar. I havent had much time to play gt4 lately. :) this car is very fun to drive. :) it oversteers more than most rear wheel drive cars in the game.
 
The problem is tires and suspension. Tighten the suspension, and depending on the race length, choose some suitable racing tires. I have a 755hp N1 skyline, and it hits over 400 on Sarthe, and takes the second half of the track easily, gliding round the corners
 
I used my N-spec skyline im not kidding with about 450-500hp and stock suspension, transmission. I possibly changed fly wheel clutch and it handled great. I kept it on the sports tires and turned the Stabililty controller to this Oversteer-0 Understeer-20 and the other at 0. And then u have a slight bit more oversteer but still very controllable. And i whooped the competition. And i think with this particular rave u have to use sports tires or lower.
 
i reccomend not using any asssissts. they just slow you down even though they make it easier to turn. 👎
 
Oh yeah, thanks for reminding me Gabkicks. If you are using either the traction controll or stability management, it will significantly lessen the results of the VCD tuning. Or any tuning for that matter. I also recomend turning them off.

VCD tuning dosent do anything for me

I noticed you're running a stage 1 turbo. the more power you have the more of a difference it will make. My experience was drawn from a 750 hp R32 GT-R on sport mediums.
 
I've bought the VCD ant it helped allot, car is now very steady, BUT, it is very hard to turn, it seems that wheel radius is now reduced, it is very hard to turn, is there something i can do about it...??

Next step is a Full Custom Differential, it will help tremendously and doesn't effect your Aspec points. I haven't messed with 4wd cars much but my experiences with RR, FR, MR cars, the LSD is a major contributor in turn in ability. My typical start setting for LSD on the rear is 20/40/15. This will typically make it a little loose entering a turn allowing the rear to slightly break loose and also allows for good turning during acceleration. I've seen in other threads where they recommend you turn all settings down to minimum on the front.
 
Thanks alot guys, i'll try that LSD..
I did messed with settings on VCD, it doesn't make noticeble difference when i move sliders.. I see you were mentioniong some 0-100 setting for VCD, but all i have is from 10-50..??
 
i don't know what you're talking about bro, you sure you're not just braking too late? i have a 99 skyline up to 803hp and it does just fine, i mean always on the first lap i have a little bit of trouble but all i need to do is get used to the track and find the best places to brake. ha ha ha and i still have my stock transmtion.

but ya try what inferno said....it could just be your wight distribution'
 
Ok, guys, i bought Variable LSD(that is full LSD??) and i played with settings, and i am sattisfied how the car handles now, it steers well, and it's stable, and all, but now it wont slide AT ALL :D .. I can't get him to drift, all slide.. :indiff:
I mean, i am in the U turn, i downshift to second gear, full right, full gas, and nothing, it handles to good now :) I wanna be able to do controllable drifts, when i push the gas pedal to the end, like i was able with 400 hp...
What do you suggest to do.. Now, it has 800 hp, sports medium tires, VCD, Variable LSD, etc..

i may beable to help alittle bit :)

one thing i notice with the stock skyline setting is that the springs apear to be around the wrong way. but i found the bes solution was to make them the same number and i think once you find the best number then ajust the rear springs with in 0.1 of the front

so your going to have to experiment with a number between 11. and 14.7

also put 1 extra level of stabilization on the rear then the front.

and adjust everything higher for a siffer setting or lower for a softer, which ever you pefer

hope that helps

yeah i noticed that too but i said "what the heck" and went with the stiffer rear for what would be considered instablity. but instability is relative :sly: My bro was sliding all over the place when he 1st drove it but thats not the case for me because i am used to oversteer.
 
Thanks for the tips, i will try those..
I tried turning off the VCD, and left only LSD, and i liked it that way, but that is for Time trial, i put VCD for real racing, it's easier.. :sly:
 
Try this:

SR 11.0 / 14.5
RH 86 / 96
SB 5 / 6
SR 7 / 9
C 2.0 / 1.0
T -1 / 1
St 3 / 5
Brake balance 2 / 4
ASM 0 / 0
TCS 4
VCD 10
LSD (None)

The VCD setting of 10, plus de-selecting LSD completely and not using it at all, seems to be the key to making 4-wheel-drive cars turn corners decently.
 
i had the same problem with my r32 stune, im using n3 tires , all i did was harden the front more than the rear , 15 % torque to the front. and it still pulls 430 on the back of le sarthe, i thought it was understeering badly then i realised i was going faster than my rwd cars.

Yo man you either need a mines skyline it is $200,000, or a nismo skyline, or a n1-spec 2
 
i spent a good 8 months on GT3 tuning the suspension of an R34 V-spec 2. and have pretty much got a perfect setups for the nurburgring/smooth race tracks/street courses/big power/low power/high down force/low downforce.

depending on what tyres you're using(sport soft in your case), you dont want to go too hard on the suspension. the harder the suspension, the more work the tyres are having to do, and sports tyres will easily be overwhelmed. so a spring rate of about 11/12 should be fine(harder with racing tyres).
damper settings for a smooth track can be about 7/8. for courses like le sarther and nurburgring, with lots of bumps, you want them a bit softer(5/6).
camber- just give the front a touch more, rear should be fine or you can up that a bit more(something like 2.5/1.3)
toe settings- if you're having trouble getting the nose into the corner, try -1 on the front, or a bit more. this would help with shorter tracks like autumn ring. you might find it under steering later in the corner, so maybe a 0 setting or + setting will help there. i leave the rear alone mostly, or 1 mark toe-in for stability.
i leave the front stabiliser at 4, and the rear at 5. this helps get the front to turn in a bit.

GT-R M-spec Nür '02 (R34); just did 6'27.438 at Nürburgring on rss. Car was tuned with all original modifications from Mine's including frame stiffener and wing, but I didn't even use the nitrous until the long straight. If you want it to drift, add about 5 to 8 clicks camber front & rear.
brakes 4/5
springs 9.0/9.0
height 115/156
shocks 8/7
camber 2.4/2.3
stabilizer 4/4

asm/u 0
tcs 3
downforce 30/33
