Product details
An individual Wilwood FNSL6R-ST right brake caliper, finished in anodized, is specified here. Use the 1.38/1.12/1.12-inch piston bores, 5.98-inch mounting centers and 1.10-inch rotor width to compare it with the existing brake assembly. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole braking system. The Forged Narrow Superlite 6R-ST uses radial mounting and six Thermlock insulated pistons. Radial mounting permits bracket adjustment but still requires accurate rotor centering, mounting height and pad sweep. Check the differential bores when matching an existing brake system.

Fitment & Compatibility
Choose this component around the existing rotor and bracket, including the 1.10-inch nominal rotor width and 5.98-inch mounting span. Use the right-hand caliper and keep the bleed arrangement in the specified orientation. Compare pad support, caliper offset and piston volume with the brake being replaced. Wheel size alone cannot confirm spoke or barrel clearance.
