Question Who's running cryo-treated rotors?

Ok, is anyone running cryo-treated rotors like from frozenrotors.com or something? Tirerack has these powerslot cryo-treated rotors now. I understand what cryo-treated rotors are, but are they worth it? I need better brakes on my car now BUT I don't want to give up my 16" rim/snow tire setup for the winter. Would those rotors, or something like them, with good pads be sufficient? Steel braided lines?

Depends what you're looking for. For better overall feel stainless lines and freshly flushed and bled brakes is just about the best. For more bite and more torque development along with higher temp capabilities nothing beats top quality pads (I like Ferodo DS2500) and good fluid. (Synpower is not too expensive and good from there MOTUL is the bomb.) Though any semi-race pad is going to dust alot. To alter bias and stay with the same wheels you can do the H6 rear upgrade. Then the next step is fourpot fronts, then up to twopot rears.

I have frozenrotors on the front and see less wear over this last year than before.

I've been running cryo-treated rotors since July of 2002, and have been a believer in their benefits ever since. In terms of overall brake performance, you probably won't notice anything. What you will see is longevity, and resistance to brake judder due to DTV.

I just had cryoed rotors and pads installed yesterday. Got everything from CTI Distributing....Brembo Sport Slotted and Pagid 4-2-1's. I researched the whole cryo'd vs. non beforehand, and what I found was that it seemed to me folks who had run cryoed brake components are overwhelming fans, while those who haven't say how much a waste of $ it is. But I heard enough reviews saying they got 3x the life from their cryo'd rotors, etc., to help make my decision. I only got 40k (barely) out of the stock rotors, and 20k outta pads, so hopefully the cryo process will add something in terms of longevity.

i have the ones from frozenrotor.com and it didnt feel any different only thing like everyone else says is the life of the rotor....does work better than stock though....

My Friends(Engine builder,suspesion mechanic) work at YAMAHA Factory racing team i ask him about cryo treated gears,etc,etc.And his answer is its a waste of money.

IMO cryo is good for parts like gear teeth etc that suffer wear from high contact stresses.....

For a rotor you need better strength and thermal capacity - something which I think cryo does not add

It has a similar effect as stress relieving which removes internal stresses that result from the casting process

I have used them and currently still do. In my E36 M3, same rotors - 1 set treated, the other not treated, using Hawk Blue's, the treated rotors lasted nearly 3x as long - measured in track days...

It's truly the cause of brake shuddering...not actual rotors warping.

I don't quite follow what you're saying. A rotor is nothing more then a big heat sink. Its main souce of issues comes from thermal cyclic loading. Relieving internal stresses due to casting will improve that rotors properties when it comes to durability, toughness, etc.

I've actually heard the exact opposite about cryo-treating....it's not really worth it for gears. While cryo-treating probably couldn't hurt gears, I don't think they would benefit as much when compared to a brake rotor.

Cryo-Treatment doesnt stress relieve. See some of these threads for highly technical discussions of cryo-treatment.

Quoting myself FTW!! Those cryoed rotors lasted me 80k, and the pads about 40k before even starting to show wear. My rotors are not showing any grooves, even after 80k. They're getting a bit thin though, and need to be replaced n the next few weeks.

I'll be getting cryoed slotted Brembos again and going with Ferodo DS2500's this time around. And while this is all on the same car, after I had the rotors n pads done I ugraded to an APS SR40 w/alcohol injection, so I drive spiritedly.

It now has a Tomei turbo (18g to 20g, basically) & runs e85. So now I drive a little more spiritedly. : ).

W/out some basic understanding of chemistry and physics, anyone who looks at cryotreatment is likely to say: blah.. not worth it..

I'll chime back in as well. I'm running the same rotors & pads since 2002. I've put about 34k miles on both. Pads are soon needing to be replaced, and the rotors do have wear in them. However, for how un-rotor friendly the mintex pads are, the rotors have held up pretty well.

I'll be getting a new set of OEM rotors cryo-treated at www.onecryo.com

it seems like you first have to buy your items and then send it to them to be cryotreated??

You do. So if you can find a place that sells the rotors already cryo treated, that'll most likely be cheaper and easier.
