The Cusco Type II lower arm bar for the ZZW30 MR-S is a chassis brace that links rear lower arm mounting points to reduce lateral flex and improve suspension responsiveness. Made for ZZW30 MR-S fitment, it helps maintain alignment under load and delivers more consistent handling during cornering. Installation is vehicle-specific and intended to tighten rear chassis behavior without major modification.
