Thanks Burntorange70, I would like to run 17 inch wheels as well for the street. How wide of a 17 can I run? What kind of backspacing would I be able to run. I also have some 15 inch wheels with 4.5 inches of backspacing that I want to run slicks on as well. Would I be able to fit a 275/60/15 withput having to raise the back of the car?
