Wilwood Front 12.88-Inch Rotor Kit with Red FNSL6R Calipers for Honda Civic/Acura Integra (2013–2024), GT Slotted

The street FNSL6R front package combines six-piston Superlite calipers, 12.88-inch rotors, separate hats and braided flexlines. BP-10 pads and stainless pistons distinguish this configuration from the related road-race assembly. Red calipers and 12.88-inch GT slotted rotors are the selected configuration. Based in Camarillo, California, Wilwood Engineering was established by Bill Wood in 1977. Its disc brake systems serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are matched to the requirements of the whole system.

Fitment & Compatibility

Use the exact Civic and Integra rows below: Honda Civic trims have individual ranges within 2013–2024, while Acura Integra Base and A-Spec are listed for 2023. The retained hub register, mounting bosses and wheel dimensions must match the kit. The installation sheet notes that the Civic factory line/ABS bracket may need its hole enlarged for the new M10 flexline fitting. Confirm all year, model and brake-package details against the application table below, including the notes attached to each row.
