Wilwood 140-16679-Y Forged Narrow Superlite Radial Front Disc Brake Kit - Yellow

The Wilwood 140-16679-Y Forged Narrow Superlite Radial (FNSL4R) Front Disc Brake Kit is engineered for high-performance street and track use on import vehicles. This complete bolt-on kit delivers race-proven stopping power with premium components matched and balanced from the ground up.

At the heart of the kit is Wilwood's FNSL4R 4-piston radial-mount caliper in a striking yellow powdercoat finish, combining lightweight forged construction with a narrow profile designed to clear tight wheel packages. The kit pairs these calipers with 11.10" to 12.19" diameter HD or SRP series drilled and slotted e-coat rotors, which improve heat dissipation, reduce fade, and resist corrosion for long service life.

Key Features:

• FNSL4R Forged Narrow Superlite Radial 4-piston calipers in yellow powdercoat finish
• HD or SRP series drilled and slotted e-coat rotors — 11.10" to 12.19" diameter for enhanced cooling and wet-weather performance

• Direct bolt-on fitment to the front strut — no additional brackets or adapters required

Wilwood's BP-10 Smart Pads deliver confident, consistent braking whether on the street or at the track, with a high-temperature friction formula that resists glazing and fade under repeated hard stops.
