The Impreza WRX has a great base platform. The factory sway bars on the WRX are not very effective for track duty due to is small size.
Increasing the diameter of your sway bars will have two main effects. They will modify handling balance in terms of steering bias
(understeer or oversteer), and they will increase roll resistance. The installation of a larger rear sway bar will provide a more neutral handling feel with oversteer when you want it.
This sway bar has two adjustment settings.
Includes polyurethane bushings for the sway bar.
