I run the stock Si wheels with 225/45/17 Direzza z1 star specs for autocross. Dropped probably 1-1.5 inches on Pro-Cs and I don't rub at all.
I was running about 38-39 all around but it was on a REALLY cold day (autocross at 20 degrees :woot:) so they warmed up during runs a lot more I'm sure.
For street 35 should be fine.

I know my star specs heated up like crazy out on the track, and we were constantly letting air out. So for the first run you should run what you brung, and for the next few runs constantly monitor your tire pressure, because it will probably go way up
