If improving performance is on your to-do list, installing a set of aftermarket Cadillac STS sway bars should definitely be in your top five of must-haves. Unless your ride is built mostly for drag racing, in which case many don't run a front sway bar for weight transfer reasons, your Cadillac STS performance will benefit and you'll feel like you're riding on rails after installing a set of Cadillac STS sway bars.

Sway bars are actually torsion springs, and can indeed have an effect on your Cadillac STS suspension's spring rate during cornering and on rough roads. Adding aftermarket Cadillac STS sway bars, also popularly known as "anti-roll bars," is a great way to improve the overall handling of your ride. These sway bars are generally thicker than the original Cadillac STS sway bars, and are therefore stiffer. The result is less side-to-side lean in turns and less understeer, which means that your vehicle will handle better under most conditions.

A: Anti-sway bar and sway bar are two terms that mean exactly the same thing.

Q: What are sway bars? Why buy a sway bar?
A: Sway bars give your car additional stability. A sway bar is a metal bar that spans the whole entire axle and joins each side of your suspension together. Aftermarket sway bars they are usually thicker than factory ones, which means they will create a more level ride, reducing body roll and under steer. With a new sway bar, you can accelerate into turns instead of braking through them.
