Wilwood 140-15552-D Forged Narrow Superlite 6R Big Brake Front Kit with Drilled Rotors

The Wilwood Forged Narrow Superlite 6R Big Brake Front Kit (Hub) delivers exceptional braking performance and show-worthy aesthetics for American muscle cars and vintage street rods running traditional non-ABS spindles. Built around Wilwood's renowned FNSL6R forged billet six-piston calipers and 12.88" drilled rotors, this kit is purpose-engineered for enthusiasts who demand maximum stopping power alongside a visually striking brake package.

Key Features:

• Forged Narrow Superlite 6R six-piston calipers — forged billet construction provides superior strength and a slim profile for increased wheel clearance
• 12.88" drilled rotor — improves heat dissipation and reduces unsprung weight for a responsive brake feel
• Hub-style rotor mounting — designed for traditional non-ABS spindle applications on classic American muscle and custom rod platforms
• Requires 17" or larger wheels — engineered to complement modern wheel, tire, and suspension upgrades
• Multiple caliper finish and rotor design options available across the FNSL6R kit family to match any custom build aesthetic
• Ideal for dual-purpose street and track as well as high-end show car builds
• All necessary hardware and brackets included for a complete bolt-on installation

The FNSL6R big brake kit is a natural upgrade partner for wheel and suspension builds on custom show machines and high-performance street/track vehicles. The narrow caliper profile maximizes clearance between the caliper face and wheel barrel, while the drilled rotor design (suffix -D) promotes consistent cooling and a clean, purposeful look. Wilwood's broad selection of caliper finishes ensures the kit integrates seamlessly with any build's style.
