It is actually a legit beneficial process.
The proper term is Controlled Thermal Processing.

Controlled thermal processing involves more than dunking your
rotor into a vat of liquid nitrogen.

It it then precisly brought back to ambiant temp. : )
They don't hand them back to you zub-zero.
Going from -1000 degrees to
Actually round -300.

The process actually changes the molecular properties of the treated
part. Los Alamos laboratories are now studying it as we speak. it is a very
new process, hence, not hearing about it back in HS. : )
The labs know it works, they just have to figure out how.
It reduces wear significantly and helps dissipate heat
evenly to prevent warping.
The Army has very good success with treating chopper gears and you
will also find the process all throughout the racing industry.
As others have said, the part also needs to be a quality part
as it will not make up for bad heat treating.
Get good rotors and then have them treated.
