The Cusco OS rear strut bar for GH8/GRB/GVB/BR9/BM9 Impreza WRX/STi applications reinforces the rear strut towers to reduce flex and improve suspension consistency, but requires a panel cut for fitment. By tying the towers together it enhances rear stability and helps keep alignment under cornering loads. It’s intended for owners prepared to modify the panel for proper installation.
