Wilwood 140-15552-DR Forged Narrow Superlite 6R Big Brake Front Kit (Hub) Drilled Rotors Red Calipers

The Wilwood Forged Narrow Superlite 6R (FNSL6R) Big Brake Front Kit delivers a purpose-built upgrade for traditional non-ABS spindles found on American muscle cars and vintage street rods. Engineered specifically for 17-inch and larger wheels, this hub-style kit pairs beautifully with tire and suspension upgrades on custom show vehicles and dual-purpose street/track builds.

At the heart of this kit are Wilwood's forged billet six-piston FNSL6R calipers finished in bold red, combined with 12.88-inch drilled and slotted rotors for maximized bite and heat dissipation under hard braking. The narrow caliper body design provides critical clearance within tight wheel packages while still delivering serious stopping force.
