Wilwood 140-16681-DY Forged Narrow Superlite 4-Piston Front Disc Brake Kit

The Wilwood 140-16681-DY is a front disc brake kit engineered for high-performance street and race applications on import vehicles. Built around Wilwood's Forged Narrow Superlite 4-Piston Radial Mount (FNSL4R) caliper, this kit delivers exceptional stopping power with a clean, motorsport-inspired appearance.

The kit pairs the FNSL4R calipers with 11.10" to 12.19" diameter HD or SRP series drilled and slotted e-coat rotors, providing improved heat dissipation and consistent bite under demanding driving conditions. The included BP-10 compound Smart Pads deliver positive pedal response, long service life, high fade resistance, and easy cleanup — making them equally suited for track days and aggressive street driving.

Installation is straightforward: the calipers mount directly to the front strut without additional brackets or adapters, simplifying the upgrade process. Braided stainless steel brake flexlines are included to complete the installation.
