Product details
The red-caliper GTO rear package combines 12.19-inch SRP rotors with radial-mount Dynapro Dust Seal calipers. It keeps the OE parking brake in service, so the existing shoes, controls and related hardware must be checked during installation. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together within a properly matched brake system.

Fitment & Compatibility
Fits the listed 2004–2006 Pontiac GTO rear applications while retaining the original internal parking-brake mechanism. The supplied service rotors incorporate the parking-drum interface; existing hubs and parking-brake components must be serviceable.
The stock backing plate/caliper bracket and dust shield require the modifications in DS494. Brake hoses are not included. Wilwood currently lists rear flexlines 220-8756 for 2005–2006 GTO; verify the 2004 hose arrangement before ordering, because the older instruction-sheet hose reference differs.
The table below gives the detailed vehicle coverage; match the individual entry and each referenced note.
