Product details
An individual Wilwood FNSL6R-ST right brake caliper, finished in anodized, is specified here. Use the 1.62/1.12/1.12-inch piston bores, 5.98-inch mounting centers and 1.10-inch rotor width to compare it with the existing brake assembly. 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. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another.

Fitment & Compatibility
Match the 5.98-inch radial attachment to the existing bracket, then check caliper centering over the 1.10-inch nominal-width rotor. Use the right-hand caliper and keep the bleed arrangement in the specified orientation. The 1/8-27 NPT connection must use the correct fitting and seal. Check the full wheel envelope with the actual bracket and rotor installed.
