A friend is looking to buy a set of 18x9.5" rims for his 97 camaro. What backspacing is best for this setup? I don't want it sticking too far out of the fenders, but I don't want it to rub either. I searched but it wasn't very helpful.

 

You can use anything from 38mm (will be flush with outside of fender) to 56mm (in the wheel well about 3/4" further).

These are 9.5" wide wheels with a 49mm offset:

mine are 56mm offset. Pics in sig.

 

Thanks for all the help.

 

The 56 mm looks good but what does that equate to in "backspacing" terms? I'm looking at some Centerline Scorpions which come in 5, 5.5 , 6, and 7" backspacing for a 9.5" rim.

 

A 9.5" wide wheel with a 56mm offset will have a backspace of approx. 7.43". The Scorpion with a 7.0" backspace would be about a 45mm offset.

 

Thanks Fred.

 

I think it could be helpful if we included some common offset/backspacing specs for the F body in the sticky at the top of the page. It would probably cut down on the ammout of threads related to these questions (created by myself also).
