I laughed when my father told me he was running cryo-treated rotors on
his 944T race car. So, he took me out to the garage and plunked down
two sets of rotors. The set that were cryo-treated were in much
better condition. He found he got more races out of a set of
cryo-treated rotors.
This of course does not mean that it translates to the street- in this
case, high-temperature racing pads in club racing, not street driving
or even lapping days. I'm not completely convinced- but it's not a
massive stretch of the imagination, given how long we've been heat
treating metals.
