Stoptech SportStop one-piece direct replacement rotors fit stock calipers. Drilling the rotors helps with cooling for the rotors, and prolongs the brake pads against fading. The rotor finish helps prevent glazing of the pads and improves wet and dry braking performance. StopTech rotors have a durable black coating on the non-swept areas of the rotor to prevent unsightly corrosion. Quality is assured as the rotors are manufactured to meet or exceed all OE specifications.
