Brains, you did'nt have to grind anything? Not even the caliper? I have not seen a 15" whell fit with out doing this.
What back spacing were they?
Do you have spacers?

I like this idea. Other than the price.

The calipers are still as they were when GM assembled the car. No grinding at all, no spacers, etc.

Backspacing -- I don't remember for sure, but if memory serves they're 7.5 BS. I can go measure if you like.

Yes, please measure the backspace. Are those 15" XP's front & back?

Do you think it would be noticeable if I ran XP's on the back and the regular 90 series on the front?
