Wilwood Black Superlite 6R Six-Lug Front Disc Conversion, 14-Inch SRP Rotors for Listed Toyota and Lexus Models

This Wilwood Superlite 6R kit is a front 14-inch brake upgrade for Toyota Tacoma/4Runner/FJ Cruiser and Lexus GX. The larger 14-inch Spec-37 rotors retain the application-specific six-lug hats and supplied braided lines. From its Camarillo, California base, Wilwood Engineering designs disc brake systems for motorsport, street-performance and specialized needs. Founded in 1977 by Bill Wood, its range covers calipers, rotors, master cylinders, valves, fittings and brake lines chosen to work within a complete brake system.

Fitment & Compatibility

For the listed six-lug Tacoma 4 x 2/4 x 4 trims, 4Runner, FJ Cruiser, GX470 and GX460, verify the exact year and submodel rather than assuming all Toyota trucks share the hub. Dust-shield cutting is required by DS-1232; inspect full steering and suspension clearance. Models covered: GX470, 4Runner, Tacoma, FJ Cruiser and GX460. Use the complete application table at the bottom for the precise year, submodel, brake option and note attached to each row.

PMB Performance brings 20+ years of parts and fitment experience to brake-system selection. Share the actual spindle or axle details, existing brake package and wheel measurements if you need help confirming this configuration.
