Whiteline Rear Sway Bar 24mm Adjustable 2008-2021 WRX / 2008-2021 STI / 2010-2013 Legacy GT / 2009-2013 Forester XT
Whiteline's 3 hole 24mm 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. Included with this Whiteline 24mm Solid Steel Heavy Duty 3-hole adjustable Rear sway bar is the Whiteline rear sway bar support brace (KBR15).
A bigger front sway bar will give the car more understeer where a bigger rear bar will give the car more oversteer.
On the Subaru Legacy models the bar will need to be flipped upside down for better clearance of the spare tire well.
