Wilwood AERO6 Front Brake Kit for Specified GM and Ridetech Pin-Spindle Applications, Black Calipers, 15-Inch GT Rotors and Hubs

Black AERO6 six-piston calipers and 15-inch GT rotor assemblies form this front hub conversion. The package is matched to specific original GM spindle geometries and separately identified Ridetech pin-spindle installations; a model name alone does not establish compatibility. 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

Match every year and original drum/disc spindle condition below. Older Ford/Mercury applications and the listed 1963–1982 Corvette installations require the stated Ridetech PIN spindle, not a Ridetech hub spindle. DS1101 requires drilling/tapping or clearance work on certain original GM spindles. Check +0.38-inch hub offset, 19-inch wheel clearance and separately selected flexlines.

Listed model families are 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; the individual year and brake/spindle conditions remain decisive. 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.
