Reviving an old thread. I was researching on rotors and I found some interesting read on cryo treatment
cryogenic rotors - Page 2 - Rennlist Discussion Forums
cryo-treated rotors = snake oil! - NASIOC
Cryogenic Rotors: Good or Snake Oil? - Pelican Parts Technical BBS
I was also reading on RB rotors, they heat treated their rotors but do not use cryo treatment.
Seems like results vary. Hope we have some chemists/engineer here that can chime in.
