PERRIN Performance 16mm Adjustable Rear Swaybars for WRX / STI 2008-2014

Add a PERRIN Adjustable Rear Swaybar to your WRX & STI. Adding a swaybar is the easiest way to improve and fine-tune the handling of your vehicle.

PERRIN Swaybars are designed to improve handling by reducing body roll and increasing cornering performance. By reducing body roll, the lateral loads on the tires become more evenly distributed, resulting in enhanced cornering grip and overall performance improvements.

PERRIN Swaybars come in four sizes; 16mm, 19mm, 22mm, and 25mm. Driving enthusiasts will enjoy the feel of a 16mm or 19mm bar while the more race-oriented drivers will like the rigidity of the 22mm and 25mm options.

PERRIN Swaybars incorporate multiple endlink mounting holes which allow for a customizable experience. The adjustability allows you to fine-tune your handling, whether it be track or street-oriented.

PERRIN Swaybars feature centering rings that prevent swaybar movement in hard cornering. This keeps your swaybar centered and ready for the next corner.

Construction - 2008-2021 WRX & STI

PERRIN Swaybars are CNC precision bent from solid 4130 chromoly steel and feature a red powdercoat finish for protection against the elements. Each bar is laser cut and MIG-welded for precise fitment and added strength for a lifetime of performance handling.

All PERRIN Swaybars include custom polyurethane bushings for a crisp response and better turn-in. Special spiral cut pockets carved into the bushing surface extend the interval between re-greasing. All our bushings include a grease packet for your swaybar installation.
