Wilwood 140-15552-R FNSL6R Forged 6-Piston Front Big Brake Kit 12.88" Rotor Red

The Wilwood 140-15552-R is a Forged Narrow Superlite 6R (FNSL6R) Big Brake Front Disc Brake Kit featuring billet forged six-piston calipers finished in red powder coat. Engineered specifically for traditional non-ABS spindles found on American muscle cars and vintage hot rods, this kit pairs high-clamping six-piston caliper technology with a 12.88" diameter rotor to deliver exceptional stopping power and visual impact.

Key Features:

• FNSL6R Billet Forged Six-Piston Calipers — Lightweight, high-strength billet forged aluminum construction with six pistons per caliper for maximum clamping force and pedal response
• 12.88" Rotor Diameter — Large-diameter rotor provides increased thermal mass and improved heat dissipation for consistent fade-resistant braking
• Red Powder Coat Finish — Durable, corrosion-resistant red caliper finish adds a bold, high-performance appearance behind the wheel
• 17" Minimum Wheel Requirement — Designed exclusively for use with 17-inch and larger wheels, making it ideal for custom show builds and performance street/track machines
• Radial Caliper Mount — Radial mount design ensures precise caliper alignment and rigidity for consistent brake feel
• Non-ABS Spindle Compatibility — Engineered for traditional factory non-ABS spindle applications common to classic American muscle cars and custom builds
• Bolt-On Installation — Kit is application-engineered for straightforward installation without custom fabrication

The FNSL6R series is purpose-built to complement wheel, tire, and suspension upgrades on high-performance dual-purpose street and track machines as well as custom show vehicles. The combination of six-piston braking power and a wide range of available caliper finishes and rotor designs allows enthusiasts to optimize both performance and aesthetics for their individual build.
