Wilwood Aluminum ProSpindle 15-Inch Front Disc Package, Black Six-Piston AERO6 Calipers and GT Rotor Assemblies

Fit black AERO6 front calipers with 15-inch GT rotors on the documented aluminum ProSpindle setup. Check the wheel envelope and separate hub assembly. These brake components attach to the separately supplied aluminum ProSpindle and sealed hub assembly. Wilwood Engineering was established in 1977 by Bill Wood and is based in Camarillo, California. Disc brake systems and components are its focus, from brake rotors and calipers to master cylinders, valves, brake lines and fittings. Its work spans motorsport, street-performance and specialized applications, with the complete brake system determining the correct individual components.

Fitment & Compatibility

The 15.00 × 1.25-inch AERO6 package is the large-rotor selection for Wilwood aluminum ProSpindle sealed-hub kit 830-17728. Purchase that spindle/hub assembly separately and compare the complete rotor/caliper envelope in DS-1623 with the actual wheel. The documented hat uses a 1.75-inch component offset and 5 × 4.50/4.75-inch drilling. Check rotor registration, steering-arm geometry and fastener engagement. Supply compatible hydraulic hoses; this configuration is not established by a generic Mustang II suspension description. 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.
