Anyone heard of Frozen Rotors?

[JimBGM98Z]

These are cryogenic treated rotors to prevent warping. Sold at Tire Rack

Any comments?

i have heard of them before thats about it

New to me... Cryogenicaly treated :thinkin: From what i know cryogenics is the DEEP freezing of objects.... But i dont know how that would help the rotors...to make them more dense...i have no idea:dunno:

The guys here at Year One told me about it when I bought mine. Said I should send mine and have it done. They do it to all of the cars we build. Says it helps alot.

they also do that to ring and pinion gears...it stablizes the metal at the moleculer level...works very well.You can do yours at home using dry ice.

wow. cool info here.

dry ice is not gonna change the surface of a metal or affect it in any way....liquid nitrogen would

Wouldnt liq nit get the metal so cold that it could shatter from being so deep frozen?? Or does the process require light spraying of the liquid nitrogen??

Cryo Treatment today is a gradual change in temp (all the way down to -300°F), during WWII they would just dip it in liquid Nitrogen. Its used today in racing, commercial duty vehicles and aviation. Brakes for example will last quite a bit longer without warping or fading. They also use it on connecting rods and pistons, ring gears and the like.

Good job slim, he's on the money. Gradually decreasing the temp gives the metal a chance to contract in a uniform manner as it freezes. This actually does the same thing as tempering, but it results in a much more uniform and reliable consistency of metal. They don't just use liq nit any more because although it gives the metal strength, it freezes it all at once and the metal doesn't have time to contract uniformly, resulting in weak points.

BULL SHIT!

Thanks, I had a few guys tell me about it at the airport i work at. After that i looked into it, some pretty cool things they do with the cryo treatment

old racer trick is to put the r&P in dry ice for 36 hrs.......then install it


Dry ice is frozen carbon dioxide. A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). Dry ice also has the very nice feature of sublimation -- as it breaks down, it turns directly into carbon dioxide gas rather than a liquid. The super-cold temperature and the sublimation feature make dry ice great for refrigeration. For example, if you want to send something frozen across the country, you can pack it in dry ice. It will be frozen when it reaches its destination, and there will be no messy liquid left over like you would have with normal ice.

Many people are familiar with liquid nitrogen, which boils at -320 degrees F (-196 degrees C). Liquid nitrogen is fairly messy and difficult to handle. So why is nitrogen a liquid while carbon dioxide is a solid? This difference is caused by the solid-liquid-gas features of nitrogen and carbon dioxide.



dry ice is plenty cold..READ BEFORE YOU POST!!!!
