Product details
Red FNSL6R calipers surround 14-inch drilled and slotted rotors in this Corvette front kit. BP-10 pads accompany the service-brake hardware, and the two-piece rotor assembly uses aluminum hats on the retained front hubs. 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. Select individual components to meet the requirements of the complete brake system.

Fitment & Compatibility
Check the 1988–1996 Corvette entries in the table below, covering the listed standard 12-inch and heavy-duty 13-inch original front brakes. The new package uses 14.00 x 1.10-inch rotors and retains the vehicle hubs; the holes in the hats do not convert their wheel pattern. Select the optional 220-8338 front flexlines and confirm routing. Use DS-538 for bracket positioning, rotor alignment and actual wheel clearance. 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.
