About this product

Part #: 126.66077SR

StopTech Slotted Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique slotting aids with heat and brake dust dispersal, prevents glazing of the pads, adds bite and improves wet and dry braking performance. Built to last, the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation, better crack resistance and increased performance.
