Add an adjustable rear sway bar to your WRX or STI. Adding a sway bar is the easiest way to improve the handling of your vehicle.
PERRIN Performance sway bars come in four different 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 Performance sway bars incorporate multiple end link 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 Performance sway bars feature centering rings that prevent sway bar movement in hard cornering. This keeps your sway bar centered and ready for the next corner.
PERRIN sway bars are CNC precision bent from solid 4130 chromoly steel. The entire bar is heavily powder coated to fight corrosion and give it a great red finish. We laser cut and MIG weld our bar ends for precise placement and superior strength. This type of bar end will never fail and offer you a lifetime of superior handling.
All PERRIN sway bars include custom polyurethane bushings for a crisp response and better turn in. Special spiral cut pockets carved into the bushing surface extends the interval between re-greasing. Included with all of our bushings are grease for your sway bar install.
