  • High-performance 13.3'' mill-balanced vented rotors keep the braking system cool for maximum stopping in all conditions. The dual wheel bolt pattern 5 on 5'' and 5 on 5.5'' allows for use on multiple wheel applications. A premium e-coat finish is durable and resists rust.
  • Pads are high performance optimized to provide maximum surface area and reduce brake dust and noise during extreme braking. The composite-resin, semi-metallic pads increase the lifetime of the brake system.
