The EBC Brakes GD Sport Rotor Sets GD860 are high-performance brake rotors designed for sports cars and other high-performance vehicles. These rotors are made from high-quality materials and feature a unique dimpled and slotted design that helps to improve braking performance. The dimpled design helps to reduce brake fade by allowing gases to escape, while the slots help to keep the rotor surface clean and free of debris. These rotors are also coated with a black Geomet finish to prevent corrosion and provide a sleek, stylish look. The GD860 set includes two front rotors and two rear rotors, providing a complete upgrade for your vehicle's braking system.
