Cusco offers two versions of their front lower arm brace. They are constructed of high tension lightweight aluminum. The simple Type 1 brace bolts to the lower arm in 2 places and improves chassis rigidity dramatically. This is perfect for a street car that just needs an improvement over stock, but will not be overly stiff. The Type 2 connects in multiple places on the lower arm and is designed for maximum rigidity. This is great for cars that see a lot of track time and need the most possible chassis support. Whether you choose the Type 1 or 2 brace you will not be disappointed.
