The Cusco rear end power brace for Honda Civic Si (FD2) is a chassis reinforcement that requires removal of the OEM bumper beam for installation. It ties rear structural points to reduce flex and help the suspension respond more predictably under cornering. Intended specifically for FD2 Civic Si models, this member is offered for buyers prepared to remove factory components as part of the fitment process.
