Wilwood Red Front AERO6 Package for Pontiac G8 (2008–2009), Drilled/Slotted 14.25-Inch Rotors

Red AERO6 calipers pair with drilled/slotted 14.25-inch rotors and BP-10 pads in this Wilwood front conversion for the supported Pontiac G8 models. The six-piston calipers use kit-specific mounting brackets, while aluminum hats carry the Spec-37 rings on the compatible original hubs. Included front lines complete the selected connections, with exact trim and wheel identification still required before installation. 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

Compare the vehicle's year and Base, GT or GXP configuration with its own application row. Inspect the original hub face and check any prior spindle modifications against the installation geometry. Align the rotor and caliper as instructed before fitting a wheel. Nominal 18-inch diameter does not prove clearance; use the complete template at the spokes and barrel. Verify hose movement through steering travel and assess the hydraulic balance against the rear brakes.

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