Wilwood Red SX6R Front Conversion, Drilled 14 x 1.25-Inch Dynamic Rotors for Listed Corvette, XLR and Ridetech Hub-Spindle Installations

Red six-piston SX6R calipers clamp 14-inch drilled rotor rings on lug-drive aluminum hats in this front assembly. BP-10 pads and mounting components are supplied for the individually listed hub configurations, without replacement hubs or hoses. Wilwood Engineering is based in Camarillo, California; Bill Wood founded the company in 1977. Disc brake system design and manufacturing includes calipers, rotors, master cylinders, pressure valves, fittings and brake lines for motorsport, street-performance and specialized applications. Component selection must account for how the complete brake system mounts, operates and balances.

Fitment & Compatibility

Use the application rows to distinguish factory C5/C6 Corvette and XLR hubs from earlier GM/Ridetech HUB-spindle conversions. A chassis name alone does not permit factory early-GM or pin-spindle installation. DS1283, full nominal 18-inch wheel clearance and actual chassis-end hose compatibility must all be checked.

The application list names Chevy II, Corvette, Skylark, Special, Sportwagon, Chevelle, El Camino, 442, Cutlass, F85, Vista Cruiser, Beaumont, GTO, LeMans, Tempest, Gran Sport, Camaro, Cutlass Supreme, Firebird, GS 350, GS 400, Nova, GS, GS 455, Sprint, Ventura, Apollo, Omega, XLR. Verify the particular year and suspension/brake option for each model. 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.

With more than 20 years of parts experience, PMB Performance can help review the specified brake arrangement. Include the vehicle year and details of any hub, spindle or suspension changes.

Check the Installation instructions for the full assembly and wheel-clearance requirements.
