The Wilwood 140-18247-D 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 designs. This kit is engineered specifically for Nissan 240SX (1989–1998) and Skyline applications, supporting 13" to 14" large-diameter rotors for a significant upgrade in braking capacity over the factory setup.

Key Features:

• Features the Forged Narrow Superlite 6R six-piston caliper — forged billet aluminum construction for high strength and reduced unsprung weight
• Application-specific engineering ensures simplified bolt-on installation with no custom fabrication required
• Fully compatible with OE master cylinder output — no brake booster or pedal feel changes required
• Compatible with OE ABS systems where equipped
• Supports 13" to 14" big brake rotors for dramatically increased swept area and heat dissipation
• Available in multiple caliper finishes and rotor designs to complement custom wheel, tire, and suspension builds
• Ideal for show cars, high-performance street driving, and track use

The FNSL6R caliper's narrow profile allows fitment behind a wide range of aftermarket and OEM wheels, making this kit a popular choice for builds that demand both performance and style. Whether you're pushing the 240SX on a road course or building a refined street machine, this Wilwood front big brake kit delivers the stopping power and visual appeal to match your build.
