For those looking for a little more MUSCLE from there suspension, enter Perrin's 25mm front sway bar for your 2008-2014 Subaru STi.
Perrin's 25mm (1") front sway bar is made of solid steel and is clearly a man's sway bar. This is finished off with a red powder coat to prevent rust, which is a big plus if your unlucky enough to live in a salty winter state. Included is new hardware needed for installation as well as polyurethane bushings.
