The StopTech Sport Drilled & Slotted Brake Rotor is a 1-piece direct replacement upgrade for your factory braking system. This 'Front Right' rotor features cross-drilling and slotting which aids in heat and brake dust dispersal, prevents pad glazing, and improves wet weather braking performance. The black e-coat finish protects against corrosion on the non-friction surfaces. Note: This part number (127.44158R) refers to a single right-hand side rotor. For a complete front set, use with part number 127.44158L (Front Left).
