Featuring an advanced alloy with increased carbon content, these rotors provide superior thermal stability and noise reduction. The proprietary Cryogenic deep-freeze treatment aligns the metal's molecular structure, significantly extending the service life and increasing resistance to heat-induced warping. Each rotor is precision-machined for perfect fitment and features an E-Coat finish on the non-friction surfaces for maximum corrosion protection. This product is sold as a single unit (1 rotor).
