Product Details

The Wilwood ST FNSL6R caliper features a unique three-piston bore arrangement: one 1.38-inch piston and two 1.12-inch pistons, paired with a 1.10-inch rotor. This specific bore sizing is carefully chosen to balance braking force and pedal feel, making it a strong choice for performance builds where precise control is key. The FNSL6R designation indicates its forged billet aluminum construction, which is both strong and lightweight, helping to reduce unsprung mass for improved suspension response.

This caliper is designed for high-performance braking systems. The forged aluminum body not only offers excellent strength to resist flex under heavy braking loads but also helps dissipate heat effectively. The ST (Short-Track) version is optimized for applications where space might be a concern, offering substantial braking power without an excessive footprint. Its anodized finish provides a durable surface that resists corrosion and wear, ensuring longevity even in demanding conditions.

When installing this caliper, ensure you have the correct adapter brackets for your specific application, as these are typically sold separately. Proper brake fluid and bleeding procedures are essential to achieve the intended performance and pedal feel. This caliper is a significant upgrade for anyone looking to improve their vehicle's stopping power and responsiveness.
