Cryogenic rotors?
Have any of you heard of this? They say it will extend the life of pads and rotors. May be of interest for you guys who race a lot. Here is the link:

I personally think it is snake oil. I ran my first set "frozen". Didn't last a season. Since then I have just bought plain rotors. They do last a season. Granted there are other factors, but if freezing them added 100% to 300% to the life, I should have seen something. If it adds 10% (which I doubt), then it is a waste of money (at 20% to 70% added cost). Those of you running them, who haven't tried plain rotors, skip it on the next set and report back here.

I don't know about in Porsches but in other groups of track cars its pretty well established that cryo treating extends the life of rotors by a significant margin. I think Patricks suggestion makes good sense, although I imagine the users have probably already tried stock rotors and then made the switch so they may already have data.

It's all B.S. Now, if you use the K&N cryo treated air filter along with my soon-to-be-patented ram-air system, then you'll have some serious improvements! 
You can't compare rotors to rotors from season to season (even weekend to weekend). Too many variables, not the least of which is the driver!
Prove me wrong - I dare you. NO ONE has ever proven these to be better, and there's only one way to do it. Buy a new set of rotors. Have one of them treated. Leave the other one alone. Put them both on the car with new pads. Run them until something breaks or cracks. See which one lasted longer. Replace with another used rotor. See how long the other one lasts. The difference, if any, will be neglible.
Save your money and use it on driving schools where it will actually benefit you.
