Raybestos 780073PER R-300 Specialty Street Performance Replacement Front Disc Brake Rotors deliver the best design, materials and coating for each application. Drivers of high-performance vehicles who use our Performance rotors will experience a stronger bite without sacrificing smooth braking. Depending on the application, Performance rotors may come with a patented S-Groove slot maximizing pad-to-rotor contact for improved pedal feel, stronger bite, smoother braking and increased pad life. Black fusion coating gives a clean, finished look, while the Grey Fusion 4.0 coating can withstand 300 hours of saltwater exposure and reduces rust for optimal airflow and cooling. Non-directional rotation means it can be used on all four corners of the vehicle.
