Product details
The red AERO6/GT package supplies large 14-inch front discs for the specified Roadster Shop chassis hardware. BP-20 pads, aluminum hats and radial brackets are included, while the original compatible hub assemblies remain in place beneath the rotors. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; it is based in Camarillo, California, and serves motorsport, street-performance and specialized applications.
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.
