Product details
The wide-rotor FNDL combines four 1.38-inch stainless bores with a nominal 1.25-inch channel. Its forged Type III body retains the narrow pad arrangement and internal fluid passages. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines. The disc brake company was founded by Bill Wood in 1977 and is based in Camarillo, California.

Fitment & Compatibility
Confirm the wide rotor's centerline relative to the 3.50-inch lugs. Other Narrow Dynalite widths have similar external features; compare the actual bracket offset and 3.00-square-inch area before ordering.
PMB Performance has worked with brake components for over 20 years. Share the required piston sizing, rotor measurements and bracket drawing for help checking the match.
