Wilwood Black Front Dynapro Conversion with SRP 11-Inch Rotors, Specified GM/Ridetech Spindles

SRP drilled-and-slotted rotors join black four-piston dust-boot calipers in this front hub conversion. The aluminum hubs offer the documented two wheel patterns, with threaded studs distinct from the rotor attachment hardware. Wilwood Engineering’s work covers the design and manufacture of disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977 in a business now based in Camarillo, California. Its calipers, master cylinders, brake rotors, brake lines, valves and fittings must be selected around the complete system.

Fitment & Compatibility

Match every vehicle's spindle note, not just its model name. Inspect the wheel contact area on the hub and follow the spacer or hub-shield requirement in DS998; flexible brake lines are selected separately.

Documented model groups, subject to each year, submodel and spindle/axle qualification: Ford Falcon, Mustang, F-100; Mercury Comet; Chevrolet Chevy II, Corvette, Chevelle, El Camino, Malibu, Camaro, Nova, Monte Carlo; Buick Skylark, Special, Sportwagon, Gran Sport, GS 350, GS 400, GS, GS 455, Apollo; Oldsmobile 442, Cutlass, F85, Vista Cruiser, Cutlass Supreme, Omega; Pontiac Acadian, Beaumont, GTO, LeMans, Tempest, Firebird, Grand Prix, Ventura; GMC Sprint. Application distinctions include w/ Ridetech Pin Spindle; Disc Brake Spindle; Drum Brake Spindle; Drum Brake Front; Base / Base; Z/28 w/ 4 Wheel Disc; w/ O.A.I. Drum Brake Spindles; Drum Brake Spindle w/o O.A.I.

The installation reference distinguishes wheel-pad overhang from a supported stamped steel wheel. Overhang requires a 0.20-inch-thick steel spacer, 6.60 inches in diameter, part 300-11961 (listed in the installation parts list). A stamped wheel without overhang should instead use the separate 0.09-inch-thick, 6.15-inch-diameter shield 300-10716.

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.

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.
