Exactly, but don't forget that first you have the rotors and/or hubs
cryonized (I made that word up, I think) and then you have them machined. In
the same way, Tom, if you have your rotors turned after some of the stresses
have been relieved by the heating, they should be more resistant to furthur
warping. 

Excuse me, I need to go relieve my own stresses. Flush.
