If you go 18, is 18x9 or 18x8.5 a better (over all) balanced size in terms of turning/handling/grip?

 

There are too many variables here to get a straight answer. Offsets will make a difference along with what tire size you run.

 

That's kinda what I'm getting at, I'd like to run an 18" but curious as to what the best balanced size is. Do offsets effect the width. For example if I go 18x8.5 with a certain offset, it will handle the same as an 18x9?

FWIW, the autocrossers in BSP and SM are running 18x9.5 (w/ rolled fenders) or 18x10 (with replaced widebody fenders). If you want something that performs to the limit that's the size you want.

I'm also not sure exactly what you mean by "balanced". Wider tire = more grip. Stick as much rubber under the car as you can.

No, offset does not affect width.

 

ttt = to the top

ttp = Track & Tarmac Performance

 

I know a lot of guys like to run 245's on a 9"-9.5" wheel. Doesn't that lower traction by eliminating sidewall flex? Isn't that a bad thaing?

 

haha

wider rim= more rubber= better handling

 

Like I said, look at the guys actually competing at a national level.

285/30R18 on 18x9.5 seems to be the wheel/tire combination to go with.

This will require a whole bunch of camber in the front plus fender rolling on the back.
