Construction & Design

The Cusco Front Strut Bar Type OS features a one-piece aluminum construction with an oval cross-section, carefully engineered through CAD development to ensure optimal fit and performance.

The steel end brackets are precision-painted in Cusco's iconic blue, adding a touch of style and ensuring long-lasting durability.

The design emphasizes ease of installation, with brackets that bolt directly onto factory mounting points. The bar's shape and mounting hardware are engineered to distribute loads evenly across the chassis, minimizing flex and enhancing overall structural integrity. This results in improved handling precision and a more connected driving feel, especially during high-speed cornering or spirited driving sessions.
