Cusco Japan engineers the strut-tower braces, sway bars, alignment correction, and limited-slip differentials that power JDM and time-attack programs. The brand behind countless Time Attack and grassroots motorsport podiums.
The Cusco OS Rear Strut Bar is the ultimate solution for reducing rear chassis flex in your Subaru Impreza GDA. By connecting the top of the rear strut towers, this bar prevents the chassis from deforming during hard cornering, which helps your suspension maintain its geometry. The result is a more stable, responsive vehicle that feels planted and predictable, even when pushed to the limits on a winding road or track.
The Cusco OS design is not only functional but also adds a clean, professional aesthetic to your trunk area. Because it is engineered specifically for the GDA chassis, the fitment is precise, ensuring you get the most out of your suspension setup. Whether you are running stock suspension or a full coilover kit, a rear strut bar is a foundational upgrade that makes a noticeable difference in how your car handles mid-corner bumps and transitions. Invest in the longevity and performance of your vehicle with premium bracing solutions from GGCRACING.
