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

This Mustang kit substitutes SRP drilled and slotted rear rotors while keeping black four-piston FDLI calipers. Internal parking shoes and reusable original wheel-speed sensors make axle-flange clearance and the correct year-specific cable choice important installation details. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake systems and components Wilwood Engineering designs and manufactures. The Camarillo, California company was founded by Bill Wood in 1977 and supports motorsport, street-performance and specialized applications. Choose each component to match the complete system’s braking 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.
