Wilwood 70-81 FBody/75-79 A&XBody FNSL6R Frt Brk Kit 12.88in D/S Rtr Blk Caliper Use w/ PD Spindle

Wilwood is well-known for making high-performance braking systems that offer a significant step up from stock. This front big brake kit, part number 140-15982-D, is designed for classic GM F-Body (1970-1981) and A&X-Body (1975-1979) vehicles, specifically when used with Performance Disc (PD) spindles. It's a comprehensive package aimed at improving stopping power and heat management for these iconic platforms.

At the heart of this kit are the FNSL6R calipers, which feature a robust six-piston design. This multi-piston setup allows for more even pad pressure distribution across the rotor surface, leading to improved braking force and better pad wear. The calipers are finished in a sleek black powder coat for a clean look. They clamp down on 12.88-inch diameter, two-piece, dynamically balanced rotors. These rotors are built to handle the increased thermal loads associated with spirited driving or heavy-duty use, helping to resist fade and maintain consistent performance. The two-piece design also helps manage heat and can simplify rotor replacement down the line.

This kit includes everything you need to upgrade your front braking system, assuming you are using the specified Performance Disc spindles. You'll find the FNSL6R calipers, the two-piece 12.88-inch rotors, caliper mounting brackets, and all the necessary hardware to get the job done. Wilwood's focus on material science and engineering means you're getting a well-built system designed for reliable performance. This is a substantial upgrade for anyone looking to significantly enhance the braking capability of their classic muscle car.
