Cusco Strut Bar AS Rear BA4/5 Prelude

The Cusco AS Rear Strut Bar is a functional and stylish upgrade that reinforces your vehicle’s rear chassis while complementing your interior with a high-end finish. As part of Cusco’s premium AS (Aluminum Shaft) series, this rear brace uses a lightweight oval-section aluminum center bar mated to robust steel end plates, delivering a perfect balance of form and function.

By connecting the rear strut towers, this bar reduces body flex and improves stability under high cornering loads. The result is sharper rear-end response and improved predictability, particularly beneficial during hard transitions or when rotating the car through tight turns. Whether you're navigating technical mountain roads or pushing through fast sweepers, the AS Rear Strut Bar helps keep the rear of the vehicle planted and composed.

The polished aluminum shaft adds a clean, motorsport-inspired look, making it an ideal choice for builds where aesthetics matter just as much as performance. Unlike plain steel bars, the AS series combines visual appeal with engineering purpose, making it suitable for both show cars and track-ready machines.
