Wilwood Red Six-Piston Front Brake Package, Impreza/Legacy/Outback/Forester/WRX/WRX STI (1999–2021), Drilled 13.06-Inch Rotors

Red Superlite six-piston calipers pair with drilled/slotted rotor rings in this Subaru front brake package. Its 13.06-inch rotor diameter and separate aluminum hats distinguish the selected assembly from the larger 14-inch alternatives. Wilwood supplies the mounting hardware, pads and front flex lines, while correct vehicle-specific hub and upright identification remains necessary before installation. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Check each model and submodel condition, including the rear brake type and production-date split on earlier applications. Do not extend a WRX listing to a different STI or Forester generation by resemblance. Compare the original mounting points with the instructions and center the calipers over the rotors. Use the wheel diagram to assess both spokes and barrel. Confirm line connections, unrestricted steering travel and suitable hydraulic balance after the complete conversion is assembled.

Match the individual year, model, submodel and equipment conditions in the fitment table below.
