The Acura TL Anti-Roll sway Bar provides a link between left and right side suspension, A Anti-roll bar is an essential component for your Acura TL. Your Acura TL Sway bar should be chosen to match your springs. If you are planning on installing stiff springs, there is no need for a large diameter roll bar. The combination of stiff springs and small sway bar is enough to control body roll. A large diameter sway bar is necessary if you will be using relatively soft springs. This is a popular configuration since the ride is not overly harsh, but the suspension is still stiff and body roll is reduced due to the sway bar. Soft springs with a large sway bar, and stiff springs with a small sway bar accomplish virtually the same goal of providing a stable suspension and reducing excessive weight transfer. A stiff springs, small sway bar setup is generally better than a soft springs, large sway bar because stiff springs reduce front to back weight transfer. With soft springs, side to side weight transfer is controlled by the sway bar, but there is a fair amount of front to back weight transfer due to the soft springs. In other words, using soft springs can result in brake dive and acceleration squat, which is detrimental to overall handling. Stabilizer bars, anti-sway bars or sway bars, no matter what they're called, serve to keep your Acura TL flatter in a corner to improve traction.

Body roll is bad. It tends to load up the outside tires of your Acura TL, reducing traction and messing up steering. The anti-sway bar makes the suspension less independent. Sharing the suspension load from the outside tires, the sway bar transfers weight to the inside tires, which means better traction. When the sway bar is too rigid it transfers bumps on the road from one side to the other. This negates too much of the independence of the suspension for both traction and comfort. So a well tuned bar tries to find a balance for real world road conditions.
