Perrin now offers their rear sway bar in 22mm (7/8") and 25mm (1") diameters for the 02-07 WRX and STI. Both 22mm and 25mm Perrin rear sway bars are made from mandrel bent, solid 4130 steel and are sealed in an extra-thick powder coating for enhanced protection from the harsh elements. The bright-red finish on the Perrin sway bars adds a nice touch of color to your Subbie's suspension too.
The Perrin rear sway bar kits include Perrin's polyurethane sway bar bushings that don't require frequent regreasing common in other bushings. Perrin's bars features multiple end link attachment points (two on the STI and three on the WRX) so you can fine tune the sway bar to compliment your other suspension components and your particular driving style.
Perrin also includes their Stout-Mounts with the 02-07 WRX/STI 22mm and 25mm rear sway bars to replace the weak OEM mounts. Perrin Stout-Mounts are machined from solid billet aluminum and are designed to stand up to the added rigidity of the 22mm or 25mm sway bars. Perrin Stout-Mounts are the toughest sway bar mount in the industry.
