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 so you can fine tune the sway bar to compliment your other suspension components and your particular driving style.

WARNING: Cancer and Reproductive Harm
Picked up the 22mm bar and Torque Solution end links. The car has a much more neutral feeling during spirited drives. I am much more confident in the car's ability to handle turns and go where I point it. Should have been done day one.
