22+ GR86 BRZ Cusco Rear Trunk Plus Power Brace
The Cusco Rear Trunk Plus Power Brace is a functional rear chassis upgrade for the Toyota GR86 and Subaru BRZ. Designed to add rigidity across the rear trunk area, this brace helps stiffen the chassis for improved stability and a more connected feel during spirited driving, autocross, and track use.
In addition to acting as a rear chassis stiffness bar, this Cusco brace can also serve dual duty as a harness bar for compatible seat and harness setups. Finished in Cusco’s signature blue, it adds both function and a clean motorsport look to the rear interior/trunk area.
