Product details
Black DP6A six-piston front calipers pair with plain 12.19-inch rotors for the aluminum ProSpindle system. Verify the separate spindle, hub and wheels. 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
Match the six-piston Dynapro 6A brake assembly to Wilwood aluminum ProSpindle sealed-hub kit 830-17728, sold separately. The rotor measures 12.19 × 0.81 inches, with a separate hat specified at 2.135 inches offset and drilled 5 × 4.50/4.75 inches. That hat offset is a component dimension, not a vehicle wheel-track promise. DS-1614 sets the bracket, registration and wheel-envelope checks. Check steering-arm suitability and supply the hydraulic flexlines needed by the particular installation. 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.
