StopTech Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers. They feature a unique cross-drilled and slotted pattern that aids in heat and brake dust dispersal, prevents pad glazing, and improves braking performance in wet and dry conditions. The black e-coat finish provides corrosion resistance for the non-friction surfaces. This is a Right Rear (Passenger Side) rotor. For a complete rear axle set, pair with part number 127.40040L. Components included: 1x StopTech 127.40040R Slotted & Drilled Brake Rotor Right.
