Whiteline Rear Trailing Arm Front Bushing Kit 2015-2021 WRX / 2015-2021 STI / 2013-2021 BRZ

Upgrading the soft stock suspension bushing with a harder unit will take the slop out of your suspension. A harder bushing will not deflect as much during hard use keeping the suspension in its optimal position. These will transfer more noise and vibration into the cabin so they are not for the faint of heart.
