A week and no one responded?

The 3-1/2" backspace is what limits you. Most of our GTO's like right about 5" backspacing to center the wheel in the opening, and you are 1-1/2" towards the outside of the fenderwell. What size tire are you currently running and what is the clearance between sidewall and the inner fender lip? If you get really serious you will need to replace your rims with a set with more backspacing.
