Sway bars are an essential upgrade when trying to get the best handling capabilities out of your BMW. Stock sway bars allow for too much play and excessive body roll, not keeping the wheels as firmly planted as they should be. Whiteline offers their performance sway bar kits that are designed to improve your BMW's handling characteristics and come with upgraded polyurethane bushings as well.

This Whiteline 20mm sway bar gives you more grip, better handling, and better outright performance. Sway bar upgrades are one of the best dollar-for-dollar investments you can make, improving your BMW's handling dynamics without affecting the comfort or ride quality.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

In high-performance driving and competitive motorsport, precision is everything. Stock rubber bushings flex, deflect, and degrade under load, leading to inconsistent handling, delayed chassis response, and unpredictable dynamic toe and camber changes.
