Cusco rear power brace for GH8 WRX/STi applications reinforces the rear structure to limit flex and improve handling consistency. Installation requires removal of the OEM bumper beam, as noted in the product description. Once installed it helps preserve alignment and rear-end responsiveness under cornering and load without major suspension changes.
