Kartboy 2008+ Impreza Rear carrier bushings are inserts designed to fit into the rear subframe, between the voids of the factory busings. These units will help eliminate the unwanted rear subframe movement that is exhibited under hard cornering loads.

This will help to drastically increase rear suspension predictability, along with increase driving confidence.

Fits:
2008-2010 WRX
2008-2010 STI
