Wilwood Front Dynalite Brake and Integral-Hub Kit for Buick Electra/Invicta/LeSabre/Riviera/Wildcat (1961–1965), Plain 11.88-Inch Rotors

Wilwood's front Dynalite conversion combines Type III anodized four-piston calipers with plain integral rotor/hub assemblies for the listed Buick applications. The selected 11.88-inch rotors use a 1.29-inch width and work with BP-10 pads on the compatible factory drum spindle. The package includes the bearing and mounting hardware needed for that arrangement, with vehicle-year and original spindle identity established before assembly. 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.
