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.

40 PSI? Much higher than I run them on my SC. For autox, I run them at 28F/30R hot, for track 30/32.

Do u think I can drive then the 30 miles to an autocross, or should I drive to the event on my streets and change there?

I would say you are fine driving on them to the event. If I go with the RA-1's next year, I'm planning on just leaving them on all the time.

Slantnose!

Absolutely fine driving on them there.

Thanks. They have been used so dosn't want to use them up more on the street.

what size tires are you running? i'm using 225/15/50, anything less than 38 my car slides around like a piece of soap

if they have little or no tread left (which is good at the track) a police officer may pull you over.

Here is some good info on the RA1s:

http://www.philstireservice.com/page...res_toyo_1.htm

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...
