Wilwood 140-18247-DR Forged Narrow Superlite Big Brake Front Kit Drilled Rotors - 6R

The Wilwood 140-18247-DR is a front big brake kit built around the Forged Narrow Superlite 6R (FNSL6R) six-piston caliper — one of Wilwood's most capable forged aluminum performance calipers. Engineered specifically for the Nissan 240SX (S13 and S14 chassis, 1989–1998), this kit delivers a dramatic upgrade in braking capacity over the factory setup, making it an ideal choice for high-performance street driving, track days, drifting, and show car builds.

Key Features:

• Forged Narrow Superlite 6R (FNSL6R) Caliper — Six-piston forged aluminum caliper with a narrow profile for improved wheel clearance and reduced unsprung weight
• Large-diameter drilled rotor — Drilled rotor design improves heat dissipation and bite, shedding gas and debris for consistent fade-resistant braking
• Application-specific engineering — Designed as a direct bolt-on kit for the Nissan 240SX S13/S14 with no custom fabrication required
• OE master cylinder compatible — Engineered to work within OE master cylinder output parameters, maintaining proper pedal feel and pressure balance
• ABS compatible — Maintains full compatibility with factory ABS systems where equipped
• Increased thermal capacity — Vented rotor construction manages heat effectively under demanding driving conditions
• Customizable finish options — Available in a range of optional caliper colors and rotor finishes to complement wheel, tire, and suspension upgrades

The FNSL6R kit is a popular choice for Nissan 240SX owners upgrading to larger wheels and demanding more from their braking system. Whether building a dedicated track machine or a performance street car, the 140-18247-DR provides the stopping power and visual presence to match the rest of your build.
