Lets Talk Rotors: Cryo-treating

gomer_110 · 07-08-2013, 09:13 PM

Had a chance to talk to one of the metallurgist guys at work today. Apparently even in the metallurgist community is split over cryo treating. In practice it will reduce the internal stresses and therefore reduce/eliminate the formation of microcracks under heat cycling. However according to the guy I work with there is no scientific proof of the effects of cryo treating to the microstructure of the metal.

In other words, it works but no one can prove 100% why.

reviving this thread. When I was racing the 1/4 mile in my Truck....4400 lbs with me in it, I kept warping the stock rotors and thus ruining the pads as well. hitting the brakes at 110 mph was scary lol

I upgraded to powerslot cryo slotted rotors on the front...rear was drum. Never warped them again and made probably 35 1/4 mile stops on them. Braking definitely improved.

Looking to get them on the Z when that time comes
