Nissan Skyline GT-R Race Car (Calsonic) '93

[CMcMahon]

I searched, and found absolutely nothing on this car. I have no problem with the gear ratios on this car; my problem has more to do with the suspension.

Basically, I have a lot of trouble keeping the car on the track, as does my B-Spec driver. On Suzuka, Motegi, or Fuji, the car is almost guaranteed to go off the track at one point.

My current suspension is lowered almost as far as it can go (maybe 10mm higher, front and back), with the springs stiff as can be. I haven't messed with the shocks, but the toe is -1 in the front and 0 in the back. TCS is at 7, both ASM at 0. Downforce all the way. LSD is unmodified.

So, any suggestions?

Start over with suspension. If you've maxed out your springs, that's why he skidding off the track. Lowering within 10-15mm from the bottom is good. You only need to add 2 or 3 clicks to springs to compensate for the lowering. Increase camber between 2.3 and 2.5 front and 1.3 and 1.5 rear usually helps. Soften front shocks around 7/7 or 6/7 and leave rear stiff at 8/8. It's 4WD so lowering VCD to lowest will help with understeer. LSD lower front to minimum and rear varies. Depending on drive style. I like the rear end a little loose on deceleration and tight on acceleration and to engage quickly, so I use 20/40/15 as a starter.

I'll try that after my F1 finishes up on Le Saarthe II 24h, and I'll let you know the results.

An F1 on LeSarthe II, you're kidding right. I ran LeSarthe I, or actually Bob did, and lapped 2nd, a R92, 6 times.
I'm at work and can't get specifics for the car, I could only give tips. Please do let me know if the tips worked.

buy the largest tubo and n.o.s.
Set the dampers to 9, lower the car all the way and make sure the stabilisers at 6.
as long as the nos is on full and the downforce is up all the way you just need to choose the brake and gear settings dude 👍

Nope, I ended up ahead eight laps; he only got ahead by seven on Le Saarthe II, probably because he had to pit every four laps instead of every five.

I'll try RK's specs out in a little while, though.
