Wilwood 140-18253-R Front Big Brake Kit FNSL6R 6-Piston Caliper 14in Rotor

The Wilwood 140-18253-R is an application-specific front big brake kit built around the Forged Narrow Superlite 6R (FNSL6R) six-piston caliper and a 14-inch large diameter rotor. Engineered for Nissan Skyline models (1995–1998), this kit delivers a dramatic upgrade in braking capacity over the factory setup while maintaining full compatibility with the OEM master cylinder output and ABS functions where equipped.

Key Features:

• Forged Narrow Superlite 6R (FNSL6R) six-piston caliper for maximum clamping force and fade resistance
• 14-inch big rotor design provides increased swept area and improved heat dissipation
• Application-specific engineering ensures simplified, straightforward installation
• Fully compatible with OEM master cylinder output — no booster or master cylinder upgrade required
• Maintains ABS function compatibility where factory ABS is present
• Complements wheel, tire, and suspension upgrades on show cars and high-performance street/track builds
• Available in optional caliper finishes to match your vehicle's style
• Multiple rotor designs available to personalize braking performance and aesthetics

This front big brake kit is ideal for performance street driving, track use, and show car builds where both stopping power and visual impact are priorities. The FNSL6R caliper's forged aluminum construction keeps unsprung weight in check while delivering the rigid, consistent pedal feel expected from a six-piston monoblock design.
