Wilwood Front Plain-Rotor Dynapro Brake Conversion, Red, 11 Inches — Matched GM/Ridetech Pin Spindles

The plain-face version of this front conversion uses red Dynapro dust-boot calipers over 11-inch vented rotors. Hubs and installation hardware are supplied, while the vehicle's hydraulic supply and spindle must already suit the documented assembly. Wilwood Engineering designs and builds disc brake systems in Camarillo, California. Bill Wood established the company in 1977; it supplies brake rotors, calipers, master cylinders, valves, fittings and lines for specialized applications, street performance and motorsport. The complete brake system determines which individual components are appropriate.

Fitment & Compatibility

Read the spindle-specific row for the vehicle and compare its bearing and mounting features with DS998. Check spacer needs at the wheel face, then choose a flexline length that clears the steering and suspension.

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.
