Product details
Black AERO6 calipers and 14-inch GT rotors form this Roadster Shop front kit.

From Camarillo, California, the company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for 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.
