2002-2005 Subaru WRX Rear Rotor (single) CRYO-STOP

Stop Tech 2002-2005 WRX Rear CRYO-STOP Rotor

Cryo Stop rotors are cryogenically treated smooth faced premium rotor castings. They use the same premium rotor castings as Stop Tech slotted performance rotors but are kept smooth to reduce costs. This rotor option is meant to offer a bridge to your customers between economical OEM replacement rotors and slotted performance rotors.

While Cryo Stop rotors will not outperform their slotted counterparts, they will outperform and outlast OEM replacements because they are cryogenically treated premium rotor castings. Cryogenic treatment is a one-time process in which the rotor is cooled to negative 300 degrees and then slowly brought back to ambient temperature. This process permanently changes the rotor on an atomic level, resulting in a denser, stronger product able to withstand greater braking forces for longer periods of time. Cryo-treated rotors have a longer lifespan and can last up to 3x longer than an untreated rotor.
