Lets Talk Rotors: Cryo-treating

MightyBobo · 10-15-2012, 02:37 PM

Who's got em, if anyone? Any first-hand experience? I'd like to go with some blank cryo-treated rotors for my next set...hopefully get some better life and durability out of them on the track...

And if anyone knows, are there any cryo-treating joints in the Baltimore area? Shipping these off for treating is EXPENSIVE, obviously...

Found these on Tirerack.com, but sadly the rear pair that are cryo-treated arent on there...

Centric High Carbon Plain 125 Series Cryo Treated Rotor

I had a Corvette that had cross drilled rotors. they all developed surface cracks near the hole after each track event. I switched to cryo treating Napa rotors after going through two set of rotors. no cracking since then

I'd never track cross-drilled rotors. That's why Im sticking with blanks. But, I gotcha

cossie1600 · 10-15-2012, 04:34 PM

the class I ran in didn't allow me to convert to blank. it was either paying 40 to cryo treat them or crack the rotor every track day. it doesn't make he car stop any better. just make he rotor last longer

Ohhh, right. That's a PITA lol.

Right, I knew that, I was curious if anyone had done it on here and had good experiences with the life of the rotor improving. Looks like you answered my question! Thanks buddy!

Luckily the cost of rotors have come down quite a bit for the Z ($100), the extra $30-40 for cryo treating won't be to bad. It beats buying those two piece rotors.

the weight reduction on the 2-piece is pretty nice though

Blech, not worth the price for just HPDE-ing

Exactly, my cryo-treated rotor had no problem stopping my car from 147mph lap after lap at VIR. The same rotor without the cryo cracked after just one event

It does work but we don't know exactly why. :P We had a good thread about the physics of it on the 3balls forums but they're lost now... even had a fella willing to treat a few sets for A-B testing.

If I remember right, it's something about aligning the molecules in a way that's similar to tempering the metal - just makes it that much stronger.

cossie1600 · 10-16-2012, 11:48 AM

also I used to get rotors hot enough to turn blue. cryo treated ones seem to have less of that problem.

StangerGT · 10-16-2012, 04:40 PM

I will prolly go this route when i swap my rotors next time around. Mine seemed to hold up well last event (stock)... i think i cooked the pads a bit though.

If anyone's looking for a place to have this done, a lot of commercial heat treat shops either have the capability or can atleast point you in the right direction.

Reviving an old thread. I was researching on rotors and I found some interesting read on cryo treatment

cryogenic rotors - Page 2 - Rennlist Discussion Forums

cryo-treated rotors = snake oil! - NASIOC

Cryogenic Rotors: Good or Snake Oil? - Pelican Parts Technical BBS

I was also reading on RB rotors, they heat treated their rotors but do not use cryo treatment.

Seems like results vary. Hope we have some chemists/engineer here that can chime in.
