Suspension and brakes are stock for now. Looking to upsize rims to 17"s in anticipation of a future brake upgrade that has yet to be decided (probably 1le, C4, or wilwood conversion). I will likely lower it as well but not anything crazy, just an inch or 2. Mainly a street cruiser with the occasional track/autocross day. Its not a drag car. Mainly im looking for widths, offsets, and backspacing that will work with stock, and wondering if the same rims will work once i change the brake system.

The wheels are 17" x 9.5" and will fit stock brakes and also just about any aftermarket kit out there. Used with great success on autocross cars and weigh several lbs less than other wheels of the same size.

 

so what is the offset, backspacing, and tire sizes needed for that size rim

 

Offset is 0mm, BS is 5.25". 17" x 9.5"

275-40-17 is the size you want, but can run anything from a 245 to a 285 if you want.
