I don't have any personal experience with the frozen rotors, but the stock rotors seem to last quite well.
Besides at the price the frozen would have to last more than twice as long as the stock rotors in order to provide any real savings. Jeff C 81 SC |

I just talked to a friend of mine who has a civil engineer degree in area of material physics.
This is what he said: Steel has crystaline structure...if you want to make it to stand up to more stress, you either try to change the "spin" of those crystals or you can use thermical treatment to try to make many layers of crystals with different "spin" characteristics ... He thinks that cooling down metal will just make molecules move less and less and will thus not alter any characteristics, it will actually "freeze" whatever the structure there is... You can draw your own conclusion from this...personally, i think it's to no use.

Well, actually I disagree. I had the same questions, so I discussed this issue with my wife (who happens to be a chemical engineer). Cryo technology is grounded in good science...it does work. I won't attempt to explain the details of it (since I'm certainly not the brains in the family) but the cryogenic process allows for the physical structure of the metal to be changed (it fills microscopic voids) thus making it more dense which results in strengthening of the metal and in turn more resistant to heat. They actual use this process on a number of other things as well, for example, I know of a snowmobile engine that went through this process. A number of the PCA guys up here use their rotors and swear by them. My brother also purchased a set for his car and couldn't be happier. They are pricer but IMO they're worth it (FWIW, Frozen Rotors claims they last 2 and sometimes 3 times longer than untreated rotors). Although some would just buy regular stock rotors and replace them a couple times. I will say that they may be more advantageous to those who use their car on the track regularly. Nonetheless, I plan to buy a set of frozen rotors this spring.
