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. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures complete disc brake systems and individual calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized installations.

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 has more than 20 years of experience with parts and fitment. We can help review the specified kit against your vehicle's actual spindle, axle or existing brake components and wheel-clearance information.
