STOPTECH Cryogenic Brake Rotor 125.40042CRY

Part # 125.40042

STOPTECH Cryogenic Treated Brake Rotor For drivers who need something even tougher than a standard StopTech? Sport rotor, but are not ready for a big brake kit, StopTech offers cryogenically treated Cryo? rotors.
Cryogenic treatment is a one-time stress relief process that involves both cold and heat cycling of the brake rotor. Using a proprietary computer-controlled process over a 24-hour period, the cryo machine gradually cools the rotors down to -300 ? F, then gradually brings them up to over +300? F, and finally back to room temperature. This conditioning of the rotor improves its service life, especially in fleet and emergency vehicle applications.
