A year ago, I did some reading on the subject of "frozen rotors". Most seem to agree that the life is increased from 200% to 300%.

Has anyone done this procedure on their rotors? What kind of life do you get your normal rotors? I'm at 80k miles and they are starting to get a little thin.

If they hold up like they're supposed to, I could get 160k-240K miles on my next rotors?

just a thought, but I think when people say the rotor life is increased 200-300 percent, they are talking in terms of heavy track use. In this situation rotors crack and warp way before they wear down... so maybe they mean 2-300% increase in rotor life before cracking and warpage? I have done some reading on the subject, but I don't claim to be an expert. I wouldn't think the rotors would be much more resistent to long term wear, however. Hope I helped a little.

I'm not an expert at all regarding this subject, but you might want to contact Porterfield Brakes, who does this process for information.They are very helpful. Their web site is: <a href="http://www.porterfield-brakes.com." target="_blank">www.porterfield-brakes.com.</a>

It sounds rather hokey to me, but I have heard from many racer friends (not ricers mind you) that they do make a difference.

The previous owner of my car installed frozen rotors (I believe that they were the ones from Diversified Cryogenics... i.e. frozenrotors.com).

So far, so good. I've experienced no problems with them, including one DE event at Summit Point in October. I was braking quite hard from 120 mph on the main straight every 1:40 or so, and I noticed no fade or warpage.

I don't know if I'd have the same experience with OEM Porsche rotors or not. Probably... but since I have no basis for comparison, I can only say that the frozen ones work fine.

Hope that helps.

I have the Diversified Cryogenics slotted rotors on my car. They've been on for about a year, and I have had no problem at all. As for the life span issue, only time will tell.

I had a set of frozen rotors once but I didn't see any big difference. That was on a 993 track car.

My current 944T has Big Reds with 94 3.6 turbo rotors. My plan is to treat the left and leave the right as received. Run them and see what happens.

One note, I bought a set of Coleman (no relation) rotors from Mandeville Auto Tech and they were junk. They lasted all of about 1 hour before warping and developing thermal fatigue cracking. I'd never buy a set of those again.

It would really suck to being going into a heavy braking zone and have the left side bite better than the right! <img border="0" title="" alt="[Eek!]" src="eek.gif" />

I understand your Idea, just than anything that could change the braking ability of left vs right does NOT seem like a good idea to me... <img border="0" title="" alt="[Frown]" src="frown.gif" />

I second M758's thoughts on the "good idea?" comment. Assuming frozen rotors are better, the different forces on the cars front end will most likely offset it's balance. This wouldn't be so good in a turn. Who knows if the difference will be that noticeable, though.
