They aren't cast aluminum are they?
I've heard horror stories of cast aluminum wheels becoming brittle and breaking apart from powdercoating. The GTX wheels I picked up were powdercoated and were not done properly (Chrome shouldn't be sand blasted in most cases the surface is stronger than the cast aluminum underneath), I would powder coat them again but I have no idea how much heat they were already treated to.
Just thought I'd share. I'm always over cautious when it comes to things like that. A reputable shop should know what to do.
