BSI Brakes, I don't want to start an arguement or anything, but that is not the proper formula for cryogenically tempering something. Not really sure who you got your equipment through, but the process is wrong.
As for the non-believers, the process actually works. It is now what heat treating was a hundred years ago, an infant. The fact that is was never taught in school is why there are so many sceptics. There are certain materials that it will not benifit, but the surface of what it will has only been scratched.
I'm sure I just made some friends with my first post.

had a baer brake rep tell me that his rotors are garunteed not to warp??? and he would replace them free if they did?? while he was standing right beside my c4 racecar.... i said alll rightttyy thenn ill see ya.. and walked away
some times i wonder if he would of given me 20 sets for free???

That's what is hard to determine. When heating something up into those temps, there are so many changes going on within the material itself.
One test could be identical sets of rotors, 1 treated and 1 nontreated to get real world answers. See how long each last on the track without warping. I probably would go and say that there will be an increase in rotor life, but not 3.5 times the life.

http://en.wikipedia.org/wiki/Cryogenic_hardening
Interesting page, I did see that it says that while it makes some steels harder, but that they are also more prone to fracture. Which makes sense to me, as cooling should allow crystalline structures to form which are naturally stronger but also prone to fracture along the crystal matrix. Like diamonds are hard, but can fracture.
Still, I don't see this having much effect after the rotor has been used on a road course and heated up to +1000 once or more times.
Also, the problem we face is with fracturing, not hardness.

Sorry to contradict a forum vender. We see Cryo rotors all the time at the track and they last less time then normal rotors. ie crack sooner.
Plus with my personal work with Liquid Nitrogen for over ten years, and knowing the penetrating and chilling effects of Liquid Nitrogen and not being able to find substantiated UNBIAS, Per Review Engineering Journals that would say different, if you track your car, stick with STOCK rotors.
and we all know about Drilled / milled or cast in hole rotors, these dont last longer or work better. and are a 40 year old myth that will not die.
a brake dyno does not put the stress on brake rotors that DEs, Track days let alone racing does on brakes.
Unless some one can show me those per review ( no advertising) engineering Journals . ..
Now that said, there is a huge need for great rotors, just dont cryo them.

Hey Tom how are you doing? Long time not type to.
I guess it's been 2 years since I looked in on this board but I see cryo is cropping up again.
It would be great if a new "super" rotor did show up but I am skeptical. After 3 plus years of being a Gingerman track junkee I never saw anything better the $25.00 plain Raybestos rotors for c5s. Although somebody showed up most every week with something really expensive that didn't do anything but crack.
Maybe things have changed?
Good to see you are still wearing out stuff!
Are you keeping the shiny side up?

Hey Rich.
SO how is Wilmington. They have an active Corvette club and post over in SE section.
YES have a bigger pile of old parts in the basement and side of the garage. Yup keeping the shinny side up, doors and fenders are a bit scrached though. j/k
YES that old boogus cryo crap just wont die. and still no SOLID non-bias peer review engineering data is non existent.
and yes those few cryo rotors we do see on the track crack faster then stock, even on the BMW's which normally dont have rotor problems.
Dont be a stranger.
