I talked to a couple of guys that, yes, race and they said they used to go through rotors pretty fast until they had them frozen. Now they run a couple of seasons and have saved quite a bit of money not having to buy rotors all the time. Thought it might save me money in the long run also.
I know this has been beaten to death, but...
A couple of years ago, I had the good fortune of carpooling with a couple of Russian Rocket Scientists. Literally.
One of them designed the booster stage for the Illiac-IV. The other was a metalurgist, specializing in steel. One of his accomplishments was designing the steel used in the trans-siberian pipeline. (A steel pipe full of steaming hot goo running for a thousand miles across a -60C wasteland...)
This guy knew a LOT about steel. A whole d@mn lot. So I asked him about cryogenically treating steel. We had to work through the Russian to English translations of the technical terms, but it came down to a few points:
1) Unless it was done -right-, it was useless. He needed special tests to see if was done right, and most places did it wrong.
2) Cryogenically treated steel is slipperier than non-treated steel. Slippery is NOT good for brakes.
3) The 1st time you got the rotors up to 'normal race' temperature, the treatment un-did itself.
It's possible, that (combining #2 w/ #3) that the treated rotors allow the pads to seat better/quicker, but that would be the total benefit.
