Wilwood Front ProMatrix Pads for Cobalt (2005–2010), HHR (2008–2010), Sky (2007–2010), G6/Pursuit (2005–2006), Malibu (2004–2006), Solstice (2006–2009), Ion (2004–2007) and G5 (2007–2008)

The D1028 ProMatrix front pattern appears on several GM compact and roadster brake packages, with a nominal 0.74-inch thickness. Supercharged, turbocharged and standard applications must be read individually because a performance trim name does not identify the same caliper across models. A complete brake system depends on compatible component selection. Wilwood Engineering designs and manufactures disc brake systems along with calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized use. Bill Wood founded Wilwood in 1977; the company is based in Camarillo, California.
