The Raybestos Specialty line was designed with the specific needs of niche markets and unique applications in mind.Whether you manage a fleet of vehicles or are a weekend warrior looking for extra stopping power for your performance vehicle, our specialty line has you covered.Raybestos Performance Rotors with S-Groove technology deliver everything serious drivers expect. Lessons learned for Raybestos racing rotors are translated into product improvements for work trucks, fleets, family vehicles with towing capabilities, and high-performance vehicles. Particularly, towing and high-performance vehicles using S-Groove rotors experience stronger bite without sacrificing smooth braking.The patented S-Groove slot (D640,620) maximizes pad-to-rotor contact for improved pedal feel, stronger bite, smoother braking and Increased pad life. Their application-specific enhanced iron also suppresses noise and keeps brakes running cool, quiet, and vibration free. In concert with this, the cooling vanes of each rotor matches the OE configuration to further improve cooling and reduce fade, all with less noise and increased pad life.This rotor's hat is coated with a black onyx coating, improving appearance for a clean, finished look, and both the rotor inboard surface and the cooling vanes are coated with our proprietary rust-inhibiting Grey Fusion 4.0 coating for optimal airflow, cooling and aesthetics.
