Wilwood Front Black Dynapro Hub Kit with 12.19-Inch SRP Rotors, GM and Ridetech Pin Spindle Applications

This front kit combines a drilled-and-slotted rotor surface with four-piston black Dynapro calipers and aluminum hubs. Its 12.19-inch diameter changes the wheel envelope compared with the smaller 11-inch conversion. Established in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems. Its master cylinders, calipers, brake rotors, lines, fittings and valves support motorsport, street-performance and specialized applications, with each component selected for its role in the complete brake system.

Check how the wheel rests on the hub before evaluating spoke clearance. Part 300-11961 (sold separately) is the specified 6.60-inch-diameter, 0.20-inch-thick steel spacer for overhanging wheel contact surfaces. The separate 300-10716 hub shield is recommended for stamped steel wheels without overhang and measures 6.15 inches by 0.09 inch.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.

Kit may fit some 15" wheels. Check wheel clearance diagram in kit installation instructions before purchase.

Universal Flexline kits available: 220-7056 (14"), 220-7699 (16") or 220-8307 (18"). Choose correct length for your application.

An independently added universal parking-brake cable system may require cable or vehicle modifications. It is separate from this front service-brake kit.
