Wilwood Front 14.00-inch Rotor and FNSL6R Kit - Black, Drilled/Slotted, GM A/F/X-Body and Ridetech Pin Spindles (1960–1982 Applications)

This 14-inch front package pairs black FNSL6R calipers with SRP rotors and replacement wheel hubs. The original GM and Ridetech pin-spindle applications must be distinguished before fitting the brackets or checking the changed wheel position. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its component range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines. The complete braking arrangement determines which individual components are appropriate.

This version pairs black calipers with SRP drilled-and-slotted 14-inch rotors. Drilled rotors are mostly chosen for looks on a street-driven car. If the car will run repeated track sessions, the GT slotted kit (140-9804) is the safer pick, since drilled holes can crack under sustained heat. The drilled rotors are also offered with red calipers (140-9804-DR) or polished calipers (140-9804-DP).

Fitment & Compatibility

Match the exact spindle entry in the table below before choosing this 14-inch hub kit. Original GM A/F/X-body disc/drum installations and the listed Ridetech pin-spindle conversions have different selection requirements; the Ford, Mercury and Corvette entries require their specified modified hardware. Some early GM spindles need machining as illustrated in DS-565. Compared with the OE mounting face, the supplied hubs add 0.38 inch per side on drum-brake applications and 0.09 inch on disc-brake applications. Verify tire/fender clearance and choose the proper separate hydraulic lines. Nominal minimum wheel diameter: 18 in; 457.2 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
