StopTech CryoStop High Carbon Rotor - Front

StopTech Sport Rotors are also available with an optional cryogenic treatment. Although cryogenic treatment is invisible to the naked eye, many fleet customers are sold on its ability to extend the service life of the brake rotor. Deep cryogenic treatment is a one-time process that permanently improves the performance and wear characteristics of metal components, from brake rotors and engine parts to machine tools and gear sets. All new StopTech Sport Rotors may be ordered with cryogenic treatment for an additional fee.This Part Fits: Year Make Model Submodel 2000 BMW 323i Base 2001-2006 BMW 325Ci Base 2001-2005 BMW 325i Base 2001-2005 BMW 325xi Base 2000 BMW 328Ci Base 1999-2000 BMW 328i Base 2001-2002 BMW Z3 Coupe 2001-2002 BMW Z3 Roadster 2003-2005 BMW Z4 3.0i 2006-2008 BMW Z4 Roadster 3.0i
