The PERRIN Performance™ Lancer Evolution rear sway bar replaces the factory 22mm sway bar with the a larger 25mm PERRIN™ bar.

This larger bar will reduce unwanted body role and increase the tire contact patch with the road. Included with the PERRIN™ rear sway bar kit are new reinforced sway bar mounts. The larger diameter of the PERRIN Performance™ rear bar adds stress to the weak factory sway bar mounts. PERRIN™ Technicians have designed a new sway bar mount that will not transfer stress to the body of the vehicle and will help the sway bar perform better by locking the bar to the car.
