Ideal Set-up
I am guessing yuo are reffering to the offset of your car? If that is the case, you could run 18x8 (31 offset) and 18x9 (35 offset) for your car. You would definitely have to roll your fenders to accomodate the wheel size.
I am running 225/40/18 (F) and 255/35/18 R. My car is lowered 1.5 inches and has no problems. If you are interested in an article about rolling your fenders, I can give you a link to it.
Anyway, good luck. Feel free to contact me with anymore questions.
