Product details
The side-inlet 0.81-inch-width FNDL has four 1.75-inch stainless pistons in a forged narrow body. Its connection arrangement changes the hydraulic line access without changing the 4.80-square-inch effective piston area. Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977; it is based in Camarillo, California, and its component range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines.
