The StopTech Sport Rotor (Left Front) is a one-piece direct replacement brake disc for your factory braking system. It features a unique cross-drilled and slotted surfacing that provides improved cooling, better bite, and reduced fade under heavy braking. The black E-Coat finish protects the hat and vanes from corrosion. Part number 127.42005L is sold individually. For a complete axle set, it is recommended to pair this with the right-side rotor: 127.42005R (Right Front Slotted & Drilled Rotor).
