ECS BMW Sway Bar Kits for BMW 3 Series E46 (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.

Enhance Cornering Performance with Thicker Sway Bars

If you're looking to take on corners more aggressively, consider upgrading to thicker sway bars. Thicker sway bars provide increased stability, minimize body roll, and ensure better traction on the road, allowing for more confident and aggressive cornering. The best part is, you can enjoy improved handling without sacrificing your ride quality.

To reduce the understeering affects of a staggered wheel setup you want a balanced set of sway bars. ECS has configured this anti-roll bar set for the non-M E46 with a 27mm adjustable front bar and a 21mm rear bar. The front is adjustable to two positions to fine-tune the handling and reduce understeer. The rear bar is fixed to retain the stock sway bar link. These anti-roll bars include urethane bushings with a reinforced inner liner that eliminates squeaks and doesn't require lubrication. The bars are powder coated for durability and good looks.

These bars fit in the stock locations using the existing brackets and links. Adjustable links are not required but recommended if the car is lowered or if you have coil overs (note: the rear bar is designed to only use the stock link, heavily lowered cars should not use this kit).

The bars are adjustable so any driver can find an ideal setup for the type of driving they are doing. The sway bar becomes stiffer in the hole(s) furthest from the end of the bar. The holes at the very end of the bar are the softest setting. We would generally recommend starting out with the front bar set to the stiffer setting and adjust to your liking from there. 

This item fits the following BMWs: 
1999-2006 E46 BMW 323i 323ci 325i 325ci 328i 328ci 330i 330ci

E46 323/325/328/330i 2-way adjustable 27mm front sway bar with urethane bushings.

Sway bars are typically sold as a front and rear set to balance the handling. But a front sway bar only can also have excellent benefits, especially on a street car. Going with a larger front bar will improve steering and handling even at low-moderate speeds. Steering turn-in is faster and gives the car a more direct and responsive feel. Cars with staggered wheel fitments (a narrower front wheel compared to the rear) will especially benefit from this and help the front tire 'bite' into the road. 

ECS has specified an adjustable 27mm sway bar that has been fine-tuned for use on the E46 non-M models. Urethane bushings with a reinforced inner core that requires no lubrication are included. 

Fits RWD models only (not 325xi/330xi).

This item fits the following BMWs: 
1999-2005 E46 BMW 323i 323ci 325i 325ci 328i 328ci 330i 330ci

The ECS Tuning Billet Rear Sway Bar Mounting Kit was designed, engineered, tested and quality inspected thanks by their Research and Development team in Wadsworth, Ohio facility. ECS ensures that the highest level of precision and quality is delivered throughout rigorous long term product testing and leading edge product development methods. This kit provides your vehicle with a more rigid mounting solution from the sway bar to chassis than the OEM steel brackets. With an improved sway bar mounting bracket and the included polyurethane sway bar bushings, you can expect to achieve an increase in rear sway bar effectiveness and less body roll as a result.
