STR Prep - Wheels and Tires

Yes, too much camber gives the car uncomfortable feedback under braking, especially while turning. This also hurts the car's ability to launch for Pro Solo and on slow/tight corner exit where the car's weight is quickly shifted. Except for sweepers, I find less camber (-2-3 range) provides more precise feedback and balance with this car than when it was higher. You may find different results. There are a few in STR (specifically Guy Ankeny) that runs his camber around -4 f/r.

From pure observation, it seems like most the people on track do not run the same big bars upfront that autocrossers do. That large difference in roll bias would require different types of alignment.

I am running a 17x8 +45 wheel (team dynamic about 17.5 ish lbs) and 255 hankook rs3.the question is how much performance am i losing out on by not using a 17x9 wheel? is it worth the extra thousand bucks at this point to buy another set of wheels or should i focus my VERY limited funds toward shocks/springs this coming season?
*from what I understand* using a narrower wheel exaggerates the softness of the sidewall, so you may lose some responsiveness in quick transitions. Possibly why you have problems with oversteer.
PS - Its ok, i still love you Mat

I have a question about running 9" wheels for STR. My S2000 is pretty un-prepped (FSB and Alignment). I was wondering if I can run 9" wheels with 255's on the front on the stock suspension, or is stiffer suspension required to prevent rubbing on the fender liners? I'm looking into getting new wheels and tires for next year, but can't afford to get both wheels & suspension done.

I went 1/4" lower and the rubbing was very much reduced. I don't want to go much lower and risk my fenders now, unless I do springs that are stiffer yet.
If you don't mind never using full lock (not really needed for autocrossing) then you could do it with rolled fenders proper camber I'd bet.

My personal experience is that the suspension was required to clear the upper A-arms. The angle of the upper A-arm of a taller car with stock suspension brings it closer to the inner edge of the wheel hoop. Mine rubbed at full lock even with the car fairly low (but not as low as others here have stated).

I'd be keeping the stock rims for daily driving, so the 9" rims would just be for auto-x, therefore not having full lock would probably be ok.
I have heard before that having more negative camber helps with rubbing on the fenders as well. Is this the case? I don't yet have a camber kit, and am running right about -1.8 in the front right now.

It is legal as long as you don't change the outside profile of the fender. In other words roll the inner lip flat to the fender but don't push the whole fender out. And that's pretty much required to have anywhere close to the ride height people are running.
More negative camber tucks the wheel in so it helps with rubbing on the fenders, however you also can have problems on the other side with the a arms and the inner part of the fender and it will hurt that. It's all a balancing act.
I did suspension first so I can't speak as to whether it's possible to run the wheels or not. I would also suspect that it will probably work with a roll and without going to full lock.

If you run a high offset (+60-63) at stock hieght and stock shocks with a swaybar you won't rub. I ran that set-up for my first half a season of autocrossing.
