Got some frozen rotors...

Mr Paddle.Shift · 10-18-2003, 11:48 AM

I don't know what bumped into my head. I ordered a set of frozen rotors for my E46 rear axle. Slotted and frozen to be exact. Still waiting for the OEM fronts to wear out so that I can get frozen ones as well.

Back to my original intention of posting...FROZEN ROTORS ARE TOO EXPENSIVE!!!!!!

So, uh, why did you get the frozen rotors?

Mr Paddle.Shift · 10-18-2003, 12:04 PM

Long story....anyway, I am seeing it as a long term kind of investment, hoping that these frozen platters will perform much better. As long as the total cost (along with my 330i front brake upgrade over the summer) does not exceed the price of a new brembo upgrade. Otherwise, I will be officially dumb.

From what I understand, cryogenically treating the rotors doesn't affect the performance, but helps them last longer by being less prone to 'warping' (and whether rotors actually warp or not is another debate).

How much more did the cryo treated ones cost? I guess depending on the application, it becomes a cost/beneifit tradeoff.

I managed to "warp" my Frozen Rotors in around 10K miles. I'm looking to get them ground down and slap them back on as I seem to have already warped their replacements.

How long do untreated rotors last you?

I know for the race car, they are legal in stock class, and I asked Alex why he didn't use them and he said it just wasn't worth the extra money

(But then again, he got OEMs sponsored)

I bought the OEM rotors that are frozen. I am guesing the freezing process is about $50 each rotor. Slotting is $45 each rotor. No cross drilling for me.

After 7 schools and 3 AutoXs, I have yet to replace the rear rotors. But I am expecting the sensor to come on anytime soon....

That sounds like good durability. How many schools does HACK get on a set of rotors? (dare we use Stuka for a data point?)

Mr Paddle.Shift · 10-20-2003, 03:29 PM

I drive slow.

It's really difficult to compare the durability of my rotors to the "crazy" people.

Remember...I had 31000 miles on my Pilot Sports before they retire. Stuka booed me for that. :roll:

I think that I warped my slotted/frozen rotors this weekned
