Product details
Drilled and slotted front rotors with black four-piston calipers suit the specified aluminum ProSpindle assembly. Verify hub mounting and hose needs. These brake components attach to the separately supplied aluminum ProSpindle and sealed hub assembly. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems along with calipers, rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications each call for components matched to the overall braking arrangement.

Fitment & Compatibility
The four-piston Dynalite kit attaches to the aluminum Wilwood 2.00-inch-drop ProSpindle and sealed-hub assembly 830-17728. Its 12.19 × 0.81-inch rotor/hat uses the documented 5 × 4.50/4.75-inch hub drilling. Obtain the spindle/hub assembly separately and verify the actual steering arrangement; Mustang II-style geometry alone is not a vehicle fitment guarantee. Follow DS-1613 for registration-ring seating, bracket alignment and wheel clearance. Suitable hydraulic hoses are 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.
