Cusco Rear Strut Bar Type OS for Toyota GR Yaris GXPA16 (1C7 541 A)

The Cusco Type OS rear strut tower brace represents a premier chassis tuning solution engineered specifically to eliminate body flex and structural deflection in high-performance hot hatches. Meticulously developed by Japanese chassis engineers using advanced stress simulation software, this premium brace connects the rear vital suspension mounting points to preserve factory suspension geometry under heavy cornering loads and high-G track maneuvers. The centerpiece features an ultra-lightweight, hollow aluminum bar extruded into a specialized oval cross-section, flawlessly optimizing the balance between structural mass reduction and torsional rigidity. This premium core is securely anchored by high-strength, heavy-duty steel end plates painted in the iconic, trademarked Cusco blue to guarantee a perfect structural fit onto the vehicle's factory mounting points. By solidifying the rear hatch architecture, the brace improves weight distribution management and minimizes body roll, resulting in dramatically enhanced rear-end stability, superior exit traction, and a more predictable handling balance on both the street and the circuit. Designed as a direct bolt-on installation, this authentic Japanese-made performance upgrade requires minor modification to the rear interior plastics for a clean, integrated finish, making it an essential modification for any discerning automotive enthusiast pushing their platform to its absolute limits
