The Cusco rear member side power brace for Subaru models (GRB, GH8, GVB, SH5, BR9, BM9) is a targeted chassis reinforcement designed to stiffen rear mounting areas and reduce suspension movement under load. It integrates with factory points to improve predictability during cornering and heavy use. Fitment is limited to the listed chassis codes, so confirm compatibility with the vehicle designation before ordering.
