Product details
The specified aluminum ProSpindle assembly takes black six-piston front calipers and 14-inch SRP rotors. Compare the wheel profile and hub mounting. These brake components attach to the separately supplied aluminum ProSpindle and sealed hub assembly. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its product range includes brake rotors, calipers, master cylinders, valves, fittings and brake lines, selected individually to match the complete brake system.

Fitment & Compatibility
For the 14-inch Superlite conversion, use the aluminum Wilwood ProSpindle sealed-hub assembly 830-17728 rather than assuming another Mustang II-style spindle is interchangeable. The separate spindle/hub kit supports the documented 5 × 4.50/4.75-inch rotor-hat interface. DS-1615 identifies the longer caliper studs and additional bracket spacers used by this 14.00 × 1.10-inch package. Verify those components, rotor centering and the complete wheel profile. Hydraulic hoses and any application-specific steering-arm work remain separate. The front-steer arm supplied with the separate ProSpindle kit does not establish correct rear-steer geometry; rear-steer arrangements require application-specific steering arms.
