I acquired some "corvette ralley" wheels via craigslist. After looking at them, there appears to be quite a bit of offset (not measured yet though) and in the middle it is stamped 15x8 JJ.

I cannot find a reference for a 15x8 JJ wheel anywhere in the coding threads.

1. Anyone know what that code means?
2. Does a wheel with symetrical backspacing look symetrical?

thanks for your help.

If they are stock GM, probably 4" bs. The code you need is on the front by the valve stem hole, most are AZ......................
