Product Details
This is the Cusco OS-T rear strut bar, made specifically for the 1986-1991 Mazda RX-7 (FC3S chassis). A strut bar connects the tops of your rear shock towers, essentially tying them together. Doing this helps reduce body flex and chassis distortion, especially when you're cornering hard.
Cusco is well-known for making solid suspension components, and this bar is no exception. It's built with a strong steel construction to handle the stresses of spirited driving. By bracing the rear shock towers, you'll notice a more direct feel from the rear suspension and improved steering response. It's a popular modification for RX-7 owners looking to get more out of their car's handling.
Installation is straightforward, typically bolting directly to the existing shock tower mounts. Make sure to check the manufacturer's instructions for any specific details regarding installation.
