Still don't know which vehicle you're talking about....
My Blazer is an LS, 4 wheel 2004, with 6 lug 16 " wheels. I want to put 15's on it but do not know if they will fit over the calipers. It might have been special ordered,I don't know. I already bought 6 lug 15's for the rear thinking I would put them on but the calipers look like they might touch. I have seen guys cut the caliper down but I don't want to do that until I know exactly how much I can cut.
I was hoping I could find someone who has already experienced this scenario.
