want to put some pro comp rims on. 16x8 with 4inch backspace. since the backspace on my stock rims is 4.5, it shouldnt move the wheel out enough to create any fender rubbing issues, given my current setup, should it? prekey mod, t-bars almost maxed, 265/75/16 duratracs. looks like ive got enough room but i want to be sure before i order the wheels.
