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

Plain vented rotors keep an uninterrupted friction face in this red-caliper Mustang rear conversion. Four stainless pistons in each FDLI service caliper operate separately from the internal parking shoes supplied for the 2.66-inch-offset axle installation. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. Individual parts must match the complete brake system and its operating requirements.

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.
