This Cusco Rear Cross bar is an extra chassis brace that a car could always use. The 4 point bolt in brace is fitted in the trunk and adds rigidity within the chassis. An increase in response can be hand with this bar and only basic hand tools are required for installation.
May require modification to the trunk carpet.
