Wilwood Front GT 12.88-Inch Rotor Kit with Red Calipers, Honda Civic 2006–2015/CR-Z 2011–2015

GT slotted rotors and red six-piston calipers are the selected hardware in this Wilwood Honda front kit. The separate-hat construction mounts 12.88-inch vented rings to serviceable factory hubs. This is a front caliper-and-rotor conversion for the matching Civic and CR-Z brake configuration, with pads included. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

Use DS819 to confirm the installed front upright and to identify the correct hydraulic-line arrangement. Civic trims and CR-Z applications have individual year coverage; preserve those distinctions when ordering. The 2012-and-later Civic hose/ABS bracket can require a drilled mounting hole for the new flexline fitting. Verify it before assembly, along with the full conditional 17-inch wheel profile. Brake hoses are separate, and the retained hub register must seat the hat without debris or runout.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
