Product Details
The forged aluminum FNSL6R calipers in this Wilwood kit feature a six-piston design, offering a substantial increase in clamping force over stock brake systems. This robust caliper construction, combined with the 14-inch directional vane rotors, is engineered to handle the demands of spirited driving and track use, providing improved stopping power and heat dissipation. The kit is specifically designed to work with Pro-Drop spindles, ensuring proper geometry and clearance for these classic GM platforms.
Wilwood's attention to detail is evident in the components included. The directional vane rotors are crucial for directing airflow through the rotor's internal vanes, which helps to carry heat away more effectively, reducing the risk of brake fade during prolonged use. The forged aluminum calipers are not only strong but also lightweight, contributing to reduced unsprung weight, which can have a positive impact on overall vehicle handling. The black caliper finish offers a clean, performance-oriented look behind your wheels.
This kit is a comprehensive solution for upgrading the braking performance on your 1970-1981 F-Body or 1975-1979 A-Body and X-Body vehicle. It's important to note that this kit is designed to be used with specific Pro-Drop spindles; ensure your vehicle is equipped with these or compatible units before installation. Proper installation will require attention to brake line routing and bleeding procedures to ensure optimal performance and safety. Consult the manufacturer's installation guide for detailed instructions and torque specifications.
