Wilwood Rear Red Dynapro Dust-Seal Caliper/Drilled-Rotor Assembly, Subaru Impreza WRX (2006–2007), 1.10-Inch-Wide Rings

Red Dynapro Dust Seal calipers distinguish this Wilwood rear conversion for the listed Impreza WRX models. The four-piston package uses drilled/slotted 12.88-inch rings, separate aluminum hats and BP-10 pads. Its rotor hats retain the compatible factory parking-brake system, while included rear hoses connect the hydraulic calipers to the appropriate vehicle configuration. 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

Confirm the 2006–2007 year and WRX trim, with the original rear hub and parking mechanism checked directly. Follow the instructions for rotor assembly and caliper shimming; correct alignment is not established by wheel clearance alone. Inspect and adjust the retained parking shoes and cable. Compare the wheel barrel and spokes with the full template, then check hose freedom across rear suspension travel. Review the completed rear package with the car's front brakes and master cylinder.

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