Backspacing
I ordered some rims from Summit and realized that it would not fit my car, I cancelled it, now I'm going after new wheels. I know that the backspacing of our cars is 3 and 3/4's, the wheels that I want to buy are Mickey Thompson's but have a 3 and 5/16's backspace, do any one of you know if (3 5/16's) wheels will fit our (3 3/4's) cars? Thank You so much.

Re: Backspacing
You can go up to 6" backspacing on these cars without a problem, 5.5"-5.75" if your car is really lowered.
Obviously tire choice can effect this but for the most part ^

Re: Backspacing
Is the back spacing the same front and rear? I was under the impression it was different? Stock rear was 5.5" and front was less?
