Whiteline's 3 hole 18mm adjustable sway bar allows trimming of oversteer/understeer through varying the sway bars ability to resist weight transfer via increasing or decreasing the effective arm length of the sway bars mounting position. If desired you can even set one side at the "hardest" position and set the other side at the "softest" position to achieve your desired effects.

A bigger front sway bar will give the car more understeer where a bigger rear bar will give the car more oversteer.
