Wilwood Rear FDLI Calipers and 12.19-inch Plain Rotors - 2005–2014 Ford Mustang, 2.66-inch Rear Axle Offset Kit, Black

Black Dynalite Internal calipers and plain-face 12.19-inch rotors form this Mustang rear disc/drum conversion. The one-piece rotor hats enclose the supplied parking shoes, with the mounting arrangement set for the 2005–2014 axle flange and 2.66-inch offset. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded in 1977 by Bill Wood, its range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines. Component selection must account for the requirements of the complete brake system.

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.
