Blade Sport High Carbon Slotted Vented 1-Piece Rear Brake Rotors (BSD7024) by EBC®. Quantity: 2 Per Pack. These replacement brake rotors are constructed from iron with high carbon and silicone content to reduce thermal buildup, brake noise, vibration, and wear. V-shaped slots expel more heat, dust, water, and gases and are designed to indicate rotors are worn when they wear away completely. Powder coat finish provides corrosion resistance on non-contact areas. Designed for use with EBC green, yellow, red, and blue pads. The anodized layer is designed to disappear in the area that the brake pads contact the rotor.
