Product details
Red Superlite 6R calipers and 12.88 x 1.10-inch drilled/slotted discs define this Roadster Shop package. Its aluminum hats use a 1.500-inch offset, and the six-piston calipers receive the included BP-10 pad set. Wilwood Engineering, based in Camarillo, California, has designed and manufactured disc brake systems since its founding by Bill Wood in 1977. The range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

Fitment & Compatibility
The Superlite front brackets are made for the Roadster Shop Mustang II spindle/upright with the specified five-on-4.75-inch hub. Check that hardware first, then compare the 12.88-inch rotor and radial caliper envelope with the wheels. This application depends on the Roadster Shop components rather than an original Mustang model year. Follow the guide's steering-arm bracket orientation, rotor registration and shim procedure. Compatible hubs stay on the vehicle, and neither replacement hubs nor spindles are included. Hydraulic flexlines must be selected separately for the installed suspension. Nominal minimum wheel diameter: 17 in; 431.8 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
