Powerslot has a rotor that has been "Cryo-treated," which apparently means that it was cooled to relatively close to absolute zero, then slowly brought back to room temp (I think) to make the steel more resistant to heat damage.

I've heard of powerslot, and I guess it's at least a reputable brand, I'm just wondering if anybody has tried these rotors or not.

I currently have EBC slotted/dimpled rotors (with greenstuff pads), and after a little over a year (with some autocrossing on them) they're starting to crack. I need to replace them soon and was wondering if anybody new if cryo-treated rotors had any advantages.

Other suggestions for replacement rotors are also welcome (stock size - preferrably slotted).

well one thing, the say Near absolute zero temperature and define that is -300 degrees, absoulte zero is almost -460 degrees.

Its still cold. But they are 160 degrees off.
