How much grinding with a 6.5 backspacing
Here's what I did..got the grinder out, took a good bit off to start with...then got some spray can primer I think and shot the caliper and let it dry a bit..then put wheel on and gave it a few turns to see where it rubbed...then took wheel off..grind...spray...spin...grind..spray....spin until it cleared without rubbing, then I went back over it all once more for a little good measure for when the brakes got hot.
