StopTech Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers. These drilled rotors provide improved cooling and better bite compared to blank rotors. Key features include a specialized black E-Coating for superior corrosion resistance and a high-performance cross-drilled pattern for enhanced heat and gas dissipation. This part number (128.40068R) refers to a single RIGHT side rotor. For a complete front axle set, it is recommended to pair this with the left side rotor (128.40068L).
