Cusco Strut Bar OS Rear FC3S RX7

This is the Cusco OS (Over-Steering) Rear Strut Bar specifically for your 1986-1991 Mazda RX-7. It's designed to connect the tops of your rear strut towers, tying them together to create a more solid chassis. When you're cornering, especially with spirited driving, the body of your car can flex. This strut bar helps reduce that flex, which can lead to a more direct and responsive feel from the rear suspension.

Cusco is well-known for making solid suspension components, and this strut bar is no exception. It's built from strong aluminum tubing with steel mounting brackets. The aluminum construction keeps the weight down while still providing the necessary rigidity. The brackets are designed to bolt directly to the factory strut tower mounting points, making installation straightforward. You'll notice a difference in how the car handles mid-corner, with less body roll and a more planted feel.

Installing this bar is a great way to improve the handling characteristics of your FC RX-7. It's a popular upgrade for anyone looking to get more out of their car's suspension, especially if you're driving it hard or participating in track events.
