StopTech Sport Slotted Brake Rotors are premium 1-piece direct replacement brake discs for your factory braking system. The directional slotting aids in the dispersal of heat, brake dust, and gases, ensuring consistent contact between the pad and the rotor. These rotors feature a special black e-coating on the non-friction surfaces to provide long-lasting corrosion resistance. Key benefits include improved wet weather braking and enhanced initial bite. Note: This is an individual Rear Left side rotor. For a complete rear axle set, it is recommended to pair this with part number 126.40087SR (Rear Right). Part Number: 126.40087SL.
