Anyone use these? I am looking at some that Cragar makes, they are listed on Summit's website. My Toyota 4Runner's rotors seem to warp pretty quick. http://store.summitracing.com/partdetail.asp?autofilter=1&part=PWR%2D791XPR&N=700+4294907680+4294924677+4294907593+4294922533+ 4294839009+115&autoview=sku

There are other brands like Power Slot and Pro Stop that make the cryogenic rotors for around $150 ea.

Cragar cryogenic rotors operate up to 200 degrees cooler than conventional brake rotors

How do they stay cooler?

Your 4 Runner's rotors warping is because Toyota made them too small for that vehicle. Toyota actually has/had a campaign with certian trucks where they replaced the front rotors and calipers to try and fix the problem. You should not have that problem with your Camaro if you use quality parts unless you do a lot of continuous hard braking: road racing, mountain roads etc. I do not think they are necessary for a street car.
