Cryo Frozen Rotors

[Kaklikian, Gary]

Alex, I've had standard Audi rotors cyro-treated by Diversified Cryogenics.
I found this really increased the durability of the rotor, reducing stress
fractures and warping,  when used on the track with race compound pads.   I
usually just had them source the rotors, slot them and then cryo-treat.

I'd recommend cryo-treatment for track use with race pads.  For street use
with your carbon kevlar pads, I don't know if it's necessary.   Have you had
problems with the Coleman rotors?  Aren't they heat-treated and slotted?
(fwiw, I'm using standard A8 rotors initially  with my new calipers with
Porterfield 4S pads just to see how it all works. I was planning on
upgrading to Coleman's eventually mainly for the weight savings, but if
you've experienced problems with their rotors ...)
