SBD,
Were you the guy out at Streets of Willow last weekend with a Base 2001 Boxster sporting 285 V710's all around?? Whew! Screamin' times. Fastest car in Stock class. Outran everyone but 1 GT3, 1 993TT, and the new 997s with trick tranny. Even bagged a Lambo. Nice!

Yes, that was me. What a fun day. You did well too! Actually, got the gt3 by .002. And by the 2nd to last run group i caught the new 997. THat thing was soo fast in the straights. It would lose me by almost 100 yards on the front straight. Should have but on the secret weapons. 10x15 275 A6 hoosiers. If you look closely at the pic it has them on.
The 15's change the gearing to 2nd at apx 70 to 2nd at 62. I usually can drop a couple of seconds. Unfortunately, they are expensive to run and I have an event this sunday in OC that I was saving them for.

How did you fit 285's up front without rubbing?

I have Pss9's and I use a 1/4 spacer's on all 4 tires. The spacers are more for the tires hitting the pss9's collars than anything else. Car is also lowered so there is negative camber of about 2 degrees on all tires. This helps the tire's angle in a bit under the fender. The 4 tires are all on 9 inch oem rear rims. They would probably rub on 9.5 or 10's in the front. At full lock they just barely touch the wheel well in the front. Also, 285 v710's have a short side wall (24.8) which is smaller diameter than most 285 tires. You might consider a 265 on a 9 as you probably will get about the same width of contact patch as the 285's are pretty restricted to stretch to their full width on the 9's.
For example, when you put an unmounted 285 next to mounted the unmounted is actually wider.
hope that helps
