Best I found to work with my setup was 215/45/17 up front & 235/40/17 in rear, but to each their own. Bigger tires mean more neg camber. I found that when I ran 245/40/17s they where to big & & I had to run more neg camber than 235/40/17s. If you don't track much then just get smaller tires. Plus, its not like the S2 has enough torque to turn those bigfoot tires. haha

 

Buy some stock fenders

 

is the rim being a 9.5 the issue? Or is that offset it?

 

In most cases, width of the rim has little to do with whats causes the problem. A lower offset is what you should be more concerned about, which is what is making all the calculations difficult. You can easily run a 9.5" wide wheel w/o fender modifications if the offset is at or higher than +60 (ball park number); but than tire size has some play in this as well.

 

What I figured. Hell on my gto I can't even fit 9.5's without cutting the fenders. And it's a freakin v8. Amazing you can on such a tiny car.

 

People on the Racing forum that autocross their car have ran 10s all around. Which is very amazing for a car with stock body and no modifications to suspension components to clear. Not many cars car run that rear let alone the front
