Mr. Pumpkin, this is a super question! one that needs to be assured to all our readers and i feel i am more than qualified to answer correctly.

I presently work for SKIP BARBER RACING SCHOOL here in Sebring, Florida as a road racing instructor.

As far as proper pressure for your street tire, the MAXIMUM PSI stated on the sidewall is 95% of the time the correct pressure to run, what is it that makes you think 35psi is generically correct?

In some cases, usually when running your car on a autocross, or true race track, maximum pressure is actually increased a little to help the side walls from rolling over during hard cornering and to improve overall braking performance and most importantly "contact patch", BUT, only if the tires in question are in perfect condition and capable of handling the performance your asking from them in the first place, such as yours. REMEMBER, your tires are the only thing in contact with the road period, so, pressure is key to optimum performance. i feel i have started you on the right path, if you would like to hear "advanced tire tech 101" reply further!

Wouldn't YOU like to have a GTS Viper as an office? I am so lucky, and will share ANYTHING I learn day in and day out. As a matter of fact i heard Helio Castro Neves of Champ car racing today say this about being in a spin today at work (I personnally instructed Al Pacino last week, LOL! God! does he suck at driving, good thing he can act! LOL!), here it is. This relates to a manual transmission car only.

IF IN DOUBT, BOTH FEET OUT, IF IN A SPIN, BOTH FEET IN.

Also he says, when over 90mph, purposely concentrate 1 mile ahead, visually impossible, but, CONCENTRATE a mile ahead, this will help you in braking.
