Waiting to get my powerstop cross drilled sloted rotors back from the shop had them custom powder coated white in the holes.
I heard alot of horror stories about cracking but ive had 5 show cars with them on them and no problems so far i guess im just lucky?

I've used the same combo on 2 Pontiac Grand Ams for a couple of years and my last Cobalt SS. Had absolutely no trouble with them. They worked great!
