Wilwood Front Dynapro Radial/ST Road-Race Brake Kit with 11.75-Inch GT Rotors for Listed Honda Civic/Civic del Sol/Fit and Acura Integra/EL Originally Using 262 mm Rotors

This Dynapro Radial/ST conversion is for dedicated road racing on the specified four-lug Honda and Acura hub/spindle arrangement. It uses Thermlock four-piston calipers, dynamic 11.75-inch GT rotor assemblies and high-temperature BP-35 pads while retaining the matched large-bearing hubs. Wilwood Engineering has designed and manufactured disc brake systems and components since its founding by Bill Wood in 1977. The company is based in Camarillo, California, and serves motorsport, street-performance and specialized applications. Its calipers, rotors, hydraulic master cylinders, valves, fittings and brake lines need to be matched to the complete system in which they operate.

Fitment & Compatibility

The spindle must originally use 262 mm/10.32-inch rotors, or be correctly converted to that exact large-bearing arrangement. Check each Civic, Civic del Sol, Fit, Integra or Canadian EL application and the Type-R exclusion. Hoses are separate and must match the vehicle/year, while the 15-inch wheel needs extra internal clearance.

Check the application-specific restrictions for Integra, Civic, Civic del Sol, EL, Fit. A shared model name does not replace the exact year and brake/suspension configuration. Use the fitment table below to confirm year, model, trim and brake or suspension options.

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.
