Product details

This black Superlite 4R package is a rear caliper-and-bracket conversion, not a rotor kit. Four-piston calipers and pads require the specified separate 13.00-inch rear rotors from the 2005–2009 C6 Z51/J55 arrangement. Founded by Bill Wood in 1977, Wilwood Engineering designs and manufactures disc brake systems from Camarillo, California. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Individual components must be selected for the complete brake system.

Fitment & Compatibility

This kit requires customer-supplied 13.00-inch C6 Z51 rear rotors of the specified 2005–2009 J55 configuration; the calipers cannot be selected solely by the vehicle year. Use 220-8177 rear flexlines for C5 or 220-9101 for C6 as applicable, both separately supplied, and confirm the listed XLR installation individually. Front line references do not serve this rear caliper connection. Verify wheel clearance and the existing parking-brake arrangement.

Listed models: Corvette; XLR. Use the fitment table below for the individual years, submodels and equipment conditions.
