Wow! That is a significant change.

I may have a set for you to resurface in a few months when I tear the engine in my car down to install the new 9.5:1 rotors. I didn't know about this and lapped the irons myself (although I didn't remove any 0.002-0.003", more like 0.0005"). I am sure they will need it again by then if the hardness is that much different(with 10,000 miles on the clock). I should have known that there was some reason that everyone didn't just do the lapping themselves....

I will let you know if they show appreciable wear (I don't want this engine to fail anytime soon).
