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.

 

my rule of thumb is that if the numbers dont match, chances are not good. they do make spacers for our cars though. (at least to use 4th gen and corvette wheels.)

 

If you do get them you will have to buy wheel spacers. They go between the rim and the hub. They usually don't cost alot but I haven't brought any in awhile.Along with that you might have to use the lug nuts with the long neck. I haven't done a setup like that since I worked for Sears 15yrs ago.

 

How big should I buy the wheel spacers?

 

Well you just need to by the spacers enough to off set the oversized rim.
