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

Black Dynapro Dust Seal calipers and 12-inch GT-slotted rotors make up this Subaru front package. Its dual-pattern hats accommodate the documented five-lug applications, while the original hubs and spindle configuration remain decisive. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are all part of Wilwood Engineering’s range of disc brake systems and components. The Camarillo, California company was founded in 1977 by Bill Wood and designs and manufactures these products for motorsport, street-performance and specialized applications. Compatibility with the complete brake system determines the appropriate component choice.

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.

Use the fitment table below to confirm the exact model, year, trim and all numbered application notes.
