BMW Sway Bar Kits for BMW E46 M3 S54 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

The next step in tuning your car's handling - after shocks/springs and camber plates - should be a set of swaybars. Using larger front and rear sway bars will give your car better/quicker turn-in and less bodyroll in corners. These bars replace the existing sway bars on the car for a clean and simple upgrade with very little downside. Sway bars should be matched with your springs/shocks to maintain a proper handling balance. In some cases only a front or rear bar is needed to positively change the balance and make the car more neutral. We sell sway bar kits from H&R, Racing Dynamics, OE BMW upgrades, and even some of our own designs. Swaybars are sold with new bushings. New links and other hardware are strongly recommended.

Upgrade your BMW's suspension with ECS Tuning Adjustable Sway Bar End Links, designed to provide up to 60mm (2.36") of adjustability. These end links allow you to eliminate sway bar preload or fine-tune it for specific racing needs and corner balancing. When installed, they improve drivetrain clearance and enhance sway bar responsiveness by reducing deflection, ensuring superior handling. Perfect for lowered vehicles using springs, coilovers, or air-ride suspension systems, these adjustable sway bar end links allow you to remove unwanted preload caused by changes in the center-to-center distance between sway bar mounting points. By adjusting the end links to a neutral position, you eliminate sway bar preload, enhancing suspension performance in various driving conditions.

The main body of the ECS Sway Bar End Links is crafted from strong, lightweight 6061-T6 billet aluminum and anodized red for superior corrosion resistance. Featuring left and right-hand threaded center sections and machined hex wrench fittings, these end links allow for quick and easy on-the-car adjustments. Zinc-plated hardware ensures secure and lasting adjustments, while the heavy-duty ball joint ends come with weather-resistant rubber boots and stainless steel wire retainers, providing superior protection against salt, rain, and ozone for extended durability. Each kit also includes zinc-plated Nyloc nuts and hardened steel washers for secure installation and improved contact surface on the sway bar.

These end links are designed, engineered, and rigorously tested by ECS Tuning to ensure the highest quality. Whether you have a lowered or stock suspension, these adjustable sway bar end links are the perfect upgrade, offering a high-quality, heavy-duty replacement that fits your specific needs.

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. 

NOTE: For coupe models only

Upgrade your vehicle's handling performance with Powerflex polyurethane sway bar bushings. Unlike OEM rubber bushings that prioritize comfort over precision, Powerflex bushings are designed to reduce body roll and enhance cornering confidence.

Sway bars play a crucial role in transmitting cornering forces from the outside wheels to the inside wheels, ensuring your vehicle stays flat during sharp turns. However, OEM rubber bushings can lead to unnecessary body roll due to their flexible nature, compromising the effectiveness of the sway bars.

Powerflex polyurethane bushings offer a firmer alternative to OEM rubber, providing improved bar retention and minimizing sloppiness during cornering. This results in enhanced handling capabilities and a more engaging driving experience.

As the leading suspension bushing manufacturer in Europe, Powerflex leverages its expertise in polyurethane materials and advanced manufacturing techniques to produce premium bushings that meet exact-fit standards. Whether you're driving on the street or hitting the track, Powerflex bushings are built to last longer than OEM rubber counterparts while delivering superior performance.

For easy installation and prolonged service life, we recommend using Powerflex Copper Grease PCG1. This grease helps reduce squeaks and ensures optimal performance of the bushings over time.

Choose Powerflex street bushings for daily-driven vehicles with occasional autocross or track outings. For dedicated track cars seeking maximum stiffness, Powerflex Black Series bushings with a 95A durometer polyurethane material are the ultimate choice, offering 25% more stiffness than street bushings.

To top it off, Powerflex stands behind its products with a lifetime warranty for the original purchaser, providing peace of mind and assurance of quality and durability. Upgrade your suspension with Powerflex and experience the difference in handling performance.
