i say get the widest you can fit. i always here crap about this and that because of gearing. your not on an open track. You want the most possible grip at all times, and you dont have time to heat up your tires, hell you want to cool them down between runs if they get to hot.

Update: I wasn't able to score quite as much financial aid as I'd hoped, I have secured $500 worth to spend on wheels and tires, so that changes my plans a bit. Now looking to use aggressive street tires and slightly wider wheels, and sell current setup to recover some costs. RS2s are pretty damn cheap right now...
So now my goals for a wheel purchase have changed. Looking to score some 6ULs or similar in a 15x8.

Just did 2 autoxs on my new RS2s this past weekend. Amazing grip for a street tire. 205/45/16 so if you're goin wider to 225 (like I want) then you're all set.
However, the tires and mounting/balancing alone are going to run you 500...not sure where you're getting money for wheels at that point.

From a price / wear standpoint, the RS2 still has the RS3 beat. The RS2 is $25 cheaper per tire and has a higher wear rating, which I'll enjoy since these would be daily driving tires. RE-11, XS, and Z1SS don't appear to be available in the size I want.

I've gone with a set of the new Kumho XS's which cost me $388 shipped for street and autocross duty. I would like a set of 225 kook's but for the price of them I figure I would just get some r-comps and seen as I don't want to run on slicks yet, picked the best value performance 205.... the Kumho.

The 225/15's aren't ideal, but I know that Jeremy Schuster ran 225/15's for years before the 275's came out and was always one of my region's fastest. Things have changed since that car competed at an auto-x though. If you plan on doing National Tours and being competitive, the 275/15's are what you'd need.
The 255/13's are just too short unless you start playing with the final drive IMHO. I've been lucky enough to drive an ASP Z06 this year and there have been a few brief moments were we've been tickling the upper range of 2nd (72-75 mph). With the general acceptance that an upshift is about .1s added to your time, have a slightly taller 2nd gear (or more revs) and the 275 is what is needed to keep up the RX7's and their 9k redline (around 73 mph on a 4.7 rear gear).
