About cryo-ing, I haven't used them personally, but I know Fast Forward Connection does it. From what they say it sounds like it's on the up and up since they use a controlled freezer instead of chemicals like liquid nitrogen, which leaves the metal prone to temperature shock.

Starting up a year and a half old thread... but, is the PF rotor actually cross drilled? If you look at those larger pictures in the thread link on the last page where PFC schools that guy, they look more like dimples than holes... If this is the case, wouldnt it be just as resistent to cracking as a slotted piece? Also the PF rotors just look plain nice

CFD, those rotors had to be severely overheated to cause that. I guarantee that ANY rotor under the conditions those were put under would look the same. May want to consider some brake ducts hehe.

ducts are
That picture was after about 12 track days and 3-1/2 sets of pads, the spider webbing started the first day on track and just got worse. If you look at the edges there is no ridge as in no wear on the rotors.

I've done i think 4 or 5 track days on mine and i don't have any spiderwebs or cracks and the PF 2pc rotors have held up great. I don't know other than excessive heat or a manufacturing defect that could have caused those...that doesn't look normal. did you talk to PF about this? I know a guy with a gt3 that uses PF 2pc rotors and he also has nothing but good things to say about those.

Yes, I talked to PF and the pretty much told me I was lucky they lasted as long as they did, we talked about the weight of the evo and the power it makes.. To PF rotors are disposable, I had another set of their replacement rotors cryo treated, we'll see how that works out no spider webbing after the first track day.
