Wilwood Rear Black Dynapro Caliper/Rotor Conversion, Subaru Impreza WRX (2006–2007), Dust Seals and GT Slotted 12.88-Inch Rings

This Wilwood rear conversion uses black Dynapro Dust Seal radial-mount calipers and GT slotted 12.88-inch rotors for the listed 2006–2007 Impreza WRX models. The four-piston calipers use 1.00-inch bores and BP-10 pads. Separate rotor hats accommodate the compatible original parking-brake mechanism, with rear flex lines supplied for the selected installation rather than a universal rear-axle package. 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

Match WRX, WRX Limited or WRX TR to the precise year and verify the original rear hub and parking-brake arrangement. Inspect retained shoes and cables before assembling the rotor hats. Center the calipers using the bracket and shim procedure, then check parking-brake release and rotor freedom. Compare the actual wheel against the full 17-inch minimum drawing. Secure the rear hoses clear of moving components and confirm balance with the installed front brakes.
