Wilwood Front GT Slotted Brake Kit for Honda Civic/Acura Integra (2013–2024) with 12.88-Inch Rotors, Black FNSL6R

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. Black calipers and 12.88-inch GT slotted rotors are the selected configuration. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, chosen to match the complete system.

Technical Details

• Kit supplied under manufacturer part number 140-16847; one listed axle/application assembly.
• Each service caliper uses 6 stainless pistons and the Forged Narrow Superlite 6R body design. It attaches through radial mounts and carries a black powder coat finish.
• The hat specification calls for aluminum, black e-coat and an offset of 0.540 inch.
• Verify the existing hub dimensions: replacement wheel hubs are outside the scope of this package.
• A 17-inch nominal wheel is the starting point. Its spoke and barrel shape must clear the actual brake assembly.
• Mounting hardware and brake pads come with the kit. Spindles, a master cylinder and a brake booster are not included.
• The rotor friction surfaces are GT slotted. The assembly diameter is 12.88 inches; rotor width is 1.10 inch and material is Spec-37 Iron.
• An axle pad set in BP-10 compound accompanies the calipers, whose published bores are 1.62, 1.12, 1.12 inches.
• Match the retained hub to the hat holes (5 X 4.50, 5 x 4.75 inches); no new wheel-hub pattern is created.
• The specified caliper hydraulic connection is 1/8-27 NPT.
• Hose package 220-12016 is included. Keep the braided lines free of strain, abrasion and contact with moving parts.

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. Use the complete application table below to check the individual year, model, submodel, original brake configuration and attached notes.

PMB Performance brings 20+ years of parts and fitment experience to brake selection. Send the actual hub or spindle details, existing brake configuration and wheel measurements for help checking this combination.
