I have been to tirerack.com and can't find what the recommended air pressure is for the tires on a 330i with the performance package. What do you guys/gals suggest?

The BMW-recommended pressures are listed in two places: driver-side door placard & in the manual. I'll make it three places:
• 225/40ZR18 - 32 psi (39 psi for max weight)
• 255/35ZR18 - 38 psi (46 psi for max weight)
Thanks, I will be picking up mine this weekend and want to make sure I am driving 1300 miles on the correct tire pressure. Thanks again.
Quik, congrats on getting the 330 ZHP.
Personally, I think 32 is too low, and running more in the rear with a staggered setup means even more understeer than the car already has built-in, way, way too much.
UUC has a good tuning guide on their site which is impossible to find, but here's a direct link. It shows how different changes, including tire pressure, effect handling characteristics...
Setup of the Sway Barbarian
I run 36.5 front and 39.5 rear at driving temps. Never had uneven tire wear from it at all. and i run 235/255, but also ran 235/265 on same pressures.
