Description

The Wilwood FNSL6R billet forged six-piston calipers are engineered to deliver exceptional braking performance and style for classic American muscle cars and vintage rods. Designed specifically for vehicles equipped with traditional non-ABS spindles, these calipers are compatible with 13-inch to 14-inch rotors, making them ideal for high-performance street and track applications.
