I have my first autocross and track day of the season in a few weeks. I was wondering if someone could give me some tire pressure recommendations. This is the setup that I will be starting out with:

Car
1998 Boxster Base Model (2.5L)
Manual with Aero Package

SCCA Autocross STR Class Setup:
Stock 17"x 7" fronts and 17"x 8.5" rear wheels
Bridgestone RE71Rs (225/45-17 front & 255/40-17 rear)
Front LCA (this is my only suspension mod at this point)
Carbotech xp8 brake pads (or should I stick with stock for autocross?)

Track Setup (same as above with following additions/changes):
OZ 18"x8.5" fronts and 18"x10" rear wheels
Toyo R888Rs (235/45-18 front & 265/35-18 Rear)
