Product details
The anodized FNSL4R combines four 1.12-inch stainless pistons with a nominal 0.81-inch rotor-width channel. It retains 1.98 square inches of effective area and the narrow 7416 pad profile. 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.

Fitment & Compatibility
Check the narrow rotor's centerline against the radial bracket. The 5.98-inch mounting pattern is shared with wider versions, so verify offset, pad sweep and wheel clearance individually.
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.
