Anyone running square 215/40r18 on 18x7.5?
 

I don't think it will be that much different since it's the springs that's different if I remember right..... but FRS do have softer front.

Thanks guys. I'll stick to 225's then! Hopefully have them in a week if all goes as planned! If not, I'll be a sad panda.

If you're on TRD springs (or any other springs) the FRS vs BRZ suspension difference is null and void. The difference is in the spring rate.

You'll be fine on TRD springs with the wheels and tires you're looking at. Refer to the pics I linked earlier, then mentally push the wheel in by 1/4 inch and the shoulder of the tire in by 1 cm. And he's much lower than you will be.
