Cryo'd disk brake rotors

Spoke to Wilwood tech guy at a show. He says cryo is basically useless for race brakes, because when rotors get to about 800F,(as they likely will exceed on a race car), the molecular structure reverts to prior condition, before the cryo treatment.Let's just use use ceramic? Onward, roverman.

That sounds right Art. Might do some good if the brakes were vastly oversized but then that would sort of defeat the purpose. Ceramic = big bucks. Scalloped is a good choice though.

Got to be cheaper than ceramic. Same weight and heat dissipation as regular aluminum. Less thermal growth than steel with better wear than cast iron. Silicon carbide particulate is the "magic". Onward, roverman.
