Wilwood Forged Narrow Superlite 6 Left Caliper, Red / 1.62/1.12/1.12-Inch Bores / 1.25-inch Rotor Width

Red powder coat surrounds this left FNSL6R's six stainless pistons. The differential 1.62/1.12/1.12-inch bores and nominal 1.25-inch rotor-width channel define its hydraulic and rotor-width configuration. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Founded by Bill Wood in 1977, its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

Technical Details

Fitment & Compatibility

Compare the 7416 pad sweep with the rotor friction surface. Use the correct left-hand mounting and check the 5.98-inch radial bracket offset along with the required 4.04-square-inch area.

With 20+ years of experience, PMB Performance can help compare the actual brake hardware. Supply the caliper number, rotor dimensions and mounting measurements when asking about compatibility.
