Michelin Pilot Sport Air Pressure
 

I have a 2002 S, and am thinking about doing some autocrossing. Has anyone experimented with air pressures for these tires to give me a hint on where to start - tuning from there for more personal performance?

I run about 43 in the back and 40 in the front. That would be a good starting point and just adjust from there to dial it in. Remember to bring chalk along so you can measure how much tire roll you're getting. FYI.... I run pilot sports too.
