Upgrading your sway bar is the easiest way to improve vehicle handing. Sway bars increase roll resistance and modify vehicle balance. In general, adding a larger rear sway bar increases over steer, and adding a larger front sway bar increases under steer. Upgrade both front and rear sway bars to reduce body roll and tune vehicle balance to your preference. We advise a 22mm upgrade bar for most street cars. Too stiff of a bar can seriously degrade ride quality and make the car prone to sudden breakaway behavior.
Note also that we suggest upgrading BOTH front and rear bars at once. Although upgrading the rear only is less expensive, the result is a car with more roll stiffness in the rear than in the front, and you'll give away ultimate grip as a result.
