Product details
Red AERO6 calipers and drilled/slotted 14-inch discs distinguish this Roadster Shop front assembly. The six-piston bodies use 1.62/1.12/1.12-inch bores, and the bracket-and-hat arrangement is specific to the Roadster Shop Mustang II spindle installation. 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 components include calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to suit the complete brake system.

Fitment & Compatibility
Use the AERO6/14-inch assembly on the Roadster Shop Mustang II uprights described in the installation guide. The required hub application is five on 4.75 inches. Verify the caliper and wheel-spoke space before assembling the brackets at the designated steering-arm location. Set rotor registration and caliper centering with the supplied adapters and shims. This is hardware-specific custom-chassis fitment, not a general original-Mustang application. Hubs, spindles and brake hoses are separate; hose selection must accommodate complete steering and suspension movement. Nominal minimum wheel diameter: 18 in; 457.2 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
