I can agree with that, however the warping comes from density variations in the rotor. As it heats and cools the denser portions are slower to move than the not-so-dense portions. The molecules may be more tightly packed, but they will still be denser in some areas. That's why I'm reluctant to buy into them, at this time anyway.

So you're saying the warpage problem isn't really cured; it's just a "higher quality" warpage. That settles it. I'm going back to drums at all 4 corners. Ron.

Well let's just say IMHO that freezing will make them tougher and less prone to wear from harsh friction materials. The best I can speculate on the warpage issue is that they may be more 'warp-resistant' than 'warp-proof'.
BTW, the NASCAR set used drums for a long, long time - even after disc brakes were mature products.

Beav -
So what's wrong with placing magnets around your gas line? I get 150+ more Horse Power, and 10 more miles per gallon! You should see what happens when I put them around my rear view mirror!

Beav it appears to me that warping problems started with the advent of ventilated discs (rotors) and solid discs did not warp the same. Your explanation in respect of variations in density or cross section causing uneven heating and cooling adds up in every respect.
Forty years ago I raced one of the first disc brake equiped cars and the brakes were outstanding in all respects. On a dull day they could be seen running dull red. Absolutely no problems with warping and no brake fade but I must say that the rotor diameter was adequate in relation to the weight of the car.

Yes, Cryo rotors can be turned. I've had to do it.
The theory behind cryo treating them is that it changes the molecular structure of the metal, that somehow it creates a more dense and consistant material. The consistancy I think is their claim to the reduction of warpage. I'm no engineer, so I can't explain it better. My cryo rotors warped because my calipers started to stick. Calipers have been rebuilt, rotors have been turned, and for the first month, there's no warpage. Then it started to rear its ugly head again. It's a minor pulsation at this point, and only when the rotor is hot, and it hasn't gotten any worse. Oh well. VK 1.3 cents |

I saw some highlights of a road rally on Speed channel and portions of the race were at night. They showed some Subies with an interesting wheel "mod". They were lit up by glowing red rotors.
That has to be over 1000 degrees F! Kelli, this is even better than your neons.

As an aside, I had gone through 2 sets of front rotors after about 79,000 km (Yes, I like to drive hard on the twisty roads which abound here plus the salt used on our winter roads rusted them badly.) I now have 30,000 km & 2 winters on the cryo's & they seem like new. Pads are also looking good. |

Wrong context. I was referring to the ridiculous amount of money required to buy a seven pound hunk of cast iron. (o.k., maybe more, maybe less) Rotors are a long way from rocket science, but one would never know, considering their price. I wasn't singling out frozen rotors, I was referring to all rotors.

How 'bout the bucks spent for a dram of crytallized carbon that serves the purpose of making Ronnie Mervis a veddy happy campaah? Ever try to stop an SVX with a pinkie ring? Ah... The Human Condition. Gotta' marvel at it every day. Ron.
