Toyo RA-1s/Autocross
#16
RA-1's at 40 psi hot will ensure perfect results.
alot of people run them in the rain keeping the cold pressures the same as they do on a dry track not realizing that the 2-3 psi difference that the tire never achieves is significant in whether the tire grips or slips, it took me a full day of lappin in the rain to realize why my back end kept flying out... its amazing how a little difference in the PSI makes a huge difference in grip levels.

It covers temps, tire pressures, camber/caster settings.
So have you gotten the car running yet fork? Havent heard from you in a while. Good to see you still know how to ruffle some feathers.

car RAN... and by that i mean i changed all the belts/rollers and it started up again without any trouble, and all my main electronics work considering there isnt much left in there...
right now i have the front suspension completly taken off and a new one just laying there... waiting for some bolts and brake hoses in the mail, ive been really lazy with the car, but it will be done.. eventualy.
