Wilwood 140-14681 Forged Narrow Superlite Front Big Brake Hat Kit - FNSL6R 6R 14.00in

The Wilwood 140-14681 is a front big brake hat kit built around the Forged Narrow Superlite 6R (FNSL6R) six-piston caliper — one of Wilwood's most capable street and track brake solutions. Featuring a 14.00-inch rotor diameter, this kit delivers significantly elevated stopping power over stock brake systems, making it an ideal upgrade for high-performance street cars, show builds, and track machines.

Each FNSL6R kit is engineered application-specific for a straightforward installation process with full compatibility with the OE master cylinder output and ABS systems where equipped. No modifications to the master cylinder or brake booster are required, allowing for a clean, bolt-on upgrade experience.
