Product details

The anodized wide-channel FSLI pairs four 1.38-inch stainless pistons with a nominal 1.25-inch rotor width. It provides 3.00 square inches of effective piston area without changing to a different pad family. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, from calipers and brake rotors to master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized use.

Fitment & Compatibility

Choose the mounting offset for this wider body. Confirm the 7420 pad sweep, 11.75–13.06-inch rotor diameter envelope and room for the NPT inlet inside the actual wheel.

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.
