The second-gen GS rides on an independent rear setup that benefits a lot from cross-bracing underneath — this Cusco lower arm bar ties the front subframe together and cuts down on the flex you feel in tight corners. Version 2 means Cusco iterated on the original design for better fitment and coverage on the GS300, GS400, and GS430. Solid upgrade if you're pushing these cars harder than Lexus ever intended.
