Product Details
If you're looking to significantly upgrade the stopping power of your 1970-1981 F-Body or 1975-1979 A-Body and X-Body vehicle, especially when using Pro-Drop spindles, this Wilwood FNSL6R front big brake kit is a serious consideration. This kit replaces your factory front brakes with a much larger, more capable system designed to handle higher speeds and more demanding driving conditions. It's a comprehensive package that addresses the core components needed for a substantial improvement in braking performance.
At the heart of this kit are the FNSL6R calipers, which are a 6-piston design. More pistons mean more even pressure distribution across the brake pad, leading to better stopping force and heat management. These calipers are paired with large 14-inch diameter rotors, providing a greater surface area for friction and a longer lever arm to help slow your vehicle down. The rotors themselves are typically a two-piece design, often featuring a directional vane structure to help pull air through the rotor and dissipate heat more effectively. The calipers come finished in a vibrant red powder coat, adding a visual upgrade to your front end. This kit is specifically designed to work with Pro-Drop spindles, ensuring proper geometry and clearance for the larger components.
When undertaking a big brake kit installation, it's important to ensure you have all the necessary supporting components. While this kit includes the calipers, rotors, and mounting hardware, you'll want to confirm compatibility with your existing master cylinder and brake lines, or consider upgrading those as well for optimal performance. Wilwood is well-known for its performance brake systems, and this kit represents a significant step up from stock, offering improved fade resistance and pedal feel for spirited driving or track use.
