Wilwood Rear Red Brake Kit - 2005–2014 Ford Mustang, 2.66-inch Rear Axle Offset, FDLI and Drilled/Slotted 12.19-inch Rotors

Red FDLI calipers and black-coated drilled/slotted rotor hats create this Mustang rear disc and parking-brake package. The kit includes the internal parking assemblies, but compatible cables, clevises and hydraulic hoses must be selected for the car. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its component range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines. The requirements of the complete brake system govern the choice of individual components.

Fitment & Compatibility

Use the Mustang trim, year and equipment entries in the table below, then confirm the 2005–2014 axle flange and 2.66-inch offset in DS-535. Minor axle-flange modification may be needed to reinstall the original wheel-speed sensor; the guide illustrates the required clearance. The kit supplies internal drum parking-brake assemblies. Clevises and cables are separate: Wilwood specifies 330-11221 for 2005–2010 and 330-12335 for 2011–2014. The 220-9248 flexline kit is also separate; the CPB-caliper hose reference is not the hose selection for this internal-drum kit. Nominal minimum wheel diameter: 15 in; 381 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
