Anyone have the specs for rotor thickness (stock GM)? I want to put a caliper on mine and see if they're worth resurfacing. Would like to know original thickness as well as minimum. Looking around here, I thought I saw 32mm as minimum, but want to confirm that and what's full size.

This is an SS, btw.

This might help. Says nominal is 27.9 mm an discard is 26 mm.

Ah. Thanks. ok. Quick check on my crappiest one is around 28.5. And it's wavy, so resurfacing will take of a fair amount. Seems likely time to dump these and put on some good stuff.
