Product details
Slotted 15-inch front rotors and red AERO6 calipers form this ProSpindle brake package. Match the separate spindle and hub kit to the wheel profile. These brake components attach to the separately supplied aluminum ProSpindle and sealed hub assembly. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized applications require individual components matched to the complete brake system.

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.
