Hey Guys,
I am doing some track time this weekend and would appreciate some input.
This spring I picked up my 92 C2 so this will be my first time driving it on the track. Excited and nervous! In the past I ran a 944TS with 16" Toyo RA1s.
I now have 17" rims with BFG Rivals. Curious to know what tire pressure I should start with? Cold temp and warm temp?
Thanks!
Kris

I've only done 1 autocross w/ my Rivals and I think I set them to 30psi cold and didn't bother messing w/ them again. I just focused on driving.

It seemed the car got a bit more tail happy as they got hotter, but that might have just been the result of me pushing harder and braking later into corners.

Mine are 225/255 on 7/9" 17" Cup 2 wheels.

The 225/45 runs wide, looks fat on the 7" wheel compared to my old Pilot Sport PS2.

I didn't have a lot of time to play with pressures but at the Clubrace/DE I ended running at about 29 or 30 cold which went up to about 34 or 35 hot. I'd probably try a little lower if I had more time. Unfortunately, it looks like I won't make BIR this weekend.

Vandit,
good imput as you have the exact rim/tire set-up as mine. I will try 30psi and see what she feels like. I am also on stock springs and shocks.

Hal,
sorry I didn't see your response. Equally great info! I was going to check to see if you were going up. Dang I was interested in seeing you and your car up there!
