Product details
This single bridge assembly is for the FNSL4R version configured around a 0.81-inch rotor. Its 3.500-inch socket-head bolt and spacer tube restore the specified bridge arrangement across the caliper. The Wilwood Engineering range includes disc brake calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977, and it designs and manufactures these brake systems and components from Camarillo, California. The complete assembly's requirements govern which individual components belong together.
