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 Tower Bar is designed to bridge the rear strut towers of your 2005-2009 Subaru Legacy, significantly increasing rear chassis rigidity. In a vehicle with a large trunk or wagon area, the rear strut towers are prone to flex during aggressive driving. This bar effectively eliminates that movement, ensuring that your rear suspension stays planted and predictable.
By installing the Cusco OS Rear Strut Tower Bar, you are creating a more balanced and responsive vehicle. It is the perfect companion to a front strut bar, providing a complete chassis stiffening solution that transforms the way your Subaru handles. Whether you are a weekend track warrior or a daily driver looking for a more engaging experience, this rear brace is a vital component. Its sleek design ensures it fits well within your trunk, maintaining utility while providing race-grade performance. Upgrade your suspension today with high-quality parts from GGCRACING.
