Wilwood 140-13019 FNSL6R Forged Narrow Superlite 6R Front Big Brake Kit

The Wilwood 140-13019 is a front big brake kit built around the Forged Narrow Superlite 6R (FNSL6R) six-piston caliper — one of Wilwood's most capable street and track caliper platforms. This kit is engineered to deliver dramatically increased stopping power while maintaining full compatibility with factory brake system components.

Key Features:

• Forged Narrow Superlite 6R six-piston calipers — forged billet construction for maximum strength and reduced weight
• Big rotor upgrade — supports 13" to 14" (330mm–355mm) diameter rotors for significantly greater thermal capacity over stock
• Application-specific engineering — bolt-on fitment designed for simplified installation using standard hand tools
• OE master cylinder compatible — engineered for full compatibility with factory master cylinder output and ABS systems where equipped
• Multiple rotor designs available — choose from drilled, slotted, or combination rotor styles to match performance needs and aesthetics
• Multiple caliper finish options — available in a variety of anodized and powder-coat finishes to complement custom builds

The Wilwood 140-13019 FNSL6R big brake kit is an ideal upgrade for high-performance street, show car, and track-day builds where increased brake capacity and upgraded aesthetics are required. It pairs seamlessly with larger wheel and tire packages as well as aftermarket suspension upgrades.
