Summit Racing™ Extreme Performance Coated Brake Rotors

Summit Racing™ offers Extreme Performance coated brake rotors for thousands of vehicles, from the 1960s and up. They're manufactured on CNC machines using CAD-CAM design for perfect balance and alignment, then coated with silver zinc to resist corrosion. These rotors provide you with maximum stopping power, reduced warping, and longer life. The cross-drilled holes and slots provide an exit route for gasses and dust, resulting in better heat dissipation and less brake fade under hard use. Other solid-surface rotors allow gasses to create a cushion between the pad and the brake rotor, resulting in poor brake performance. The cross-drilled holes and slots clear away harmful gasses, restoring full pad-to-rotor contact. These coated rotors are a terrific performance upgrade when replacing your brakes. Order the model recommended for fitment on your vehicle.
