Product details
Use 14-inch drilled and slotted front rotors with black AERO6 calipers on the specified ProSpindle. Check hub engagement, wheel space and hose needs. 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
AERO6 calipers and 14.00 × 1.25-inch rotors form this front brake package for the separately purchased aluminum ProSpindle hub kit 830-17728. The hat has the documented 1.75-inch component offset and 5 × 4.50/4.75-inch hub interface. Compare the actual hub, steering arm and wheel with DS-1617; matching a nominal wheel diameter does not establish spoke clearance. This requires the specified ProSpindle assembly, suitable hydraulic flexlines and a steering arrangement appropriate to the vehicle. 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.
