Here, you are looking at the Perrin 19mm Rear swaybar for your WRX, STI, BRZ, or 86!

Prevent plow and improve handling with Perrin!

The only way to make your car turn, stop or go is if the entire available tire patch is hitting the surface at hand. The factory included what many regard to be a whimsical attempt to increase cornering with puny sway bars on the front and rear. PERRIN™ sees the need for far larger and stronger sway bars and now offers two choices for both ends of your car.

For street enthusiasts that simply want to attack the drive to work with more gusto, the 19mm upgrade is the ideal choice. While dedicated track hounds will delight in the increased snap now available from our 22mm offering. Each size and each end also incorporates 3adjustment holes to help you custom tailor your suspension to your specific needs and driving habits. Made from solid steel and heavily powder coated to prevent the rigors of salty roads that wreak havoc with less-worthy products. All kits include polyurethane pocketed bushings to prevent tedious re-greasing and all necessary hardware for a clean and painless installation.

Please note, 2015+ WRX / STI uses a 20mm factory bar, and this will be less stiff than the factory bar.
