Wilwood Rear Black Superlite 4R Kit with 14-Inch GT Rotors — Corvette C5/C6 (1997–2013) and Cadillac XLR (2004–2009), OE Parking Brake Retained

This black Superlite 4R rear package pairs 14-inch GT rotors with BP-20 pads for the specified Corvette and XLR applications. The original internal parking brake remains in place and must be adjusted after the new service-brake components are installed. Based in Camarillo, California, Wilwood Engineering has designed and manufactured disc brake systems and components since Bill Wood founded the company in 1977. Its work spans motorsport, street-performance and specialized applications, with a product range covering master cylinders, calipers, brake rotors, valves, fittings and brake lines. These parts must be chosen for the requirements of the entire brake system.

Fitment & Compatibility

For the listed 1997–2013 Corvette C5/C6 and 2004–2009 Cadillac XLR rear applications. The rotor hats work with the existing internal parking brake, which is retained and adjusted to factory specifications. Verify the precise brake package, hub and wheel arrangement.

The application notes call for 1/8-inch spacers with OE rear wheels. Check the DS516 template, wheel seating and stud engagement for the actual wheel. Rear hydraulic lines are separate; choose the correct model-specific connection rather than treating a front hose reference as a rear component.
