Wilwood Front Plain-Rotor and Hub Conversion, Black Dynapro Six-Piston Calipers, Wilwood ProSpindle Mounting

This Wilwood front hub package uses black Dynapro 6 calipers and plain 12.19-inch rotors for the Wilwood ProSpindle mounting arrangement. The replacement hubs carry the vented friction rings, with brackets positioning the six-piston calipers. Vehicle make alone cannot establish compatibility with this aftermarket spindle package. Wilwood Engineering was founded by Bill Wood in 1977 and 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 for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Compare the actual ProSpindle with DS643 and verify its bearing and bracket interfaces before installation. The spindle itself is not included with the brake components. Check the +0.10-inch wheel mounting change relative to the published reference, then confirm tire position and actual wheel-profile clearance. Select hydraulic lines for the chassis separately and inspect rotor centering before testing the completed system.
