StopTech Sport Slotted and Drilled Brake Rotors are 1-piece direct replacement brake discs for your factory brake system and stock calipers. They offer improved stopping performance and cooling through a patented cross-drilling and slotting pattern that aids in heat and brake dust dispersal. The rotors feature a durable black e-coat on the non-friction surfaces to prevent corrosion and maintain a clean look. This part number (127.47021L) refers to a single LEFT front rotor. For a complete axle set, it must be paired with the right-side rotor (127.47021R). Components: 1 x StopTech 127.47021L Sport Rotor (Left Front).
