Wilwood Red Dynalite Front Conversion with Plain 11-Inch Rotor/Hubs and Flexlines, Verified Factory GM and Ridetech Pin-Spindle Layouts

Red Dynalite-M calipers operate plain 11-inch iron rotor/hub assemblies in this front conversion. The integral design means there is no separate aluminum hub, while BP-10 pads, bearing/mounting parts and the front hose set accompany the matched spindle package. Founded by Bill Wood in 1977, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems plus their individual components. Its work serves specialized applications, motorsport and street-performance vehicles, with a range of calipers, brake rotors, master cylinders, valves, fittings and brake lines. A compatible complete system governs the selection of each part.

Fitment & Compatibility

Keep each model/year tied to its factory GM drum/disc spindle or Ridetech PIN-spindle condition. The older Ford/Mercury and early Corvette model listings are custom-spindle applications. Follow DS1143 for any required machining, verify the correct +0.47/-0.03-inch hub-position baseline and compare full nominal 14-inch wheel clearance.

Models represented in the detailed applications: Falcon, Comet, Chevy II, Corvette, Skylark, Special, Sportwagon, Chevelle, El Camino, Malibu, Mustang, 442, Cutlass, F85, Vista Cruiser, Acadian, Beaumont, GTO, LeMans, Tempest, Gran Sport, F-100, Camaro, Cutlass Supreme, Firebird, GS 350, GS 400, Nova, Grand Prix, GS, GS 455, Monte Carlo, Sprint, Ventura, Apollo, Omega. Each is subject to its individual year, trim and brake/suspension condition. Use the fitment table below to confirm year, model, trim and brake or suspension options.

Choose any alternative flexline for the actual route and chassis fittings, with enough travel and the correct flare connections.
