Evos have a great base for handling, however for track duty you can benefit greatly from a larger diameter rear sway bar for better handling.
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.
For the Evo or AWD platform, you will benefit most from increasing the diameter of the rear sway bar which will provide more neutral handling and better rear rotation for turn-in.
This sway bar has 3 adjustment settings.
Also includes polyurethane bushings for the sway bar.
