StopTech Drilled 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 cross-drilling 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.
