Wilwood Front 12-Inch Drilled/Slotted Rotors and Black Dynapro DS Calipers — Selected Legacy/Outback (2000–2002), Forester (2001–2011), Impreza (1999–2016) and WRX/WRX STI (2013–2021)

This Subaru front kit supplies black Dynapro DS calipers with 12-inch SRP rotors. The drilled/slotted rotor pair, radial brackets and BP-10 pads serve only the individual Impreza, WRX, Forester, Legacy and Outback configurations listed below. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded by Bill Wood in 1977, the company also produces the individual calipers, brake rotors, master cylinders, valves, fittings and brake lines used in these installations. Selection should account for how each component works within the complete brake system.

Fitment & Compatibility

Coverage is limited to the specific Subaru entries below: selected Impreza models from 1999–2016, Forester from 2001–2011, Legacy and Outback from 2000–2002, plus the listed WRX and WRX STI configurations through 2021. Model and year alone do not establish a match; confirm the original brake/spindle arrangement and wheel pattern.

DS522 uses the original front hubs with radial caliper brackets. Match the actual five-lug pattern to the hat and verify the 12-inch rotor wheel template. Front hose kit 220-12857 is separate and must have clearance through full suspension and steering travel.

Check the full application table below, including its model-year splits and brake-configuration requirements.
