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.

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.

The Powerflex BMW E24 / E28 / E32 / E34 / E36 / E39 / E46 / Z3 Rear Sway Bar Bushing – 15 mm is a specialized suspension upgrade designed to improve the performance of your BMW’s rear sway bar system. Engineered for BMW models with a 15 mm rear sway bar, this bushing provides a perfect fit and superior handling.

Key Features:

  • Precise Fit for 15 mm Sway Bars: This bushing is specifically designed for rear sway bars with a 15 mm diameter, ensuring a snug fit for a wide range of BMW models, including the E24, E28, E32, E34, E36, E39, E46, and Z3. The precise fit reduces play and ensures optimal performance of the sway bar.
  • Improved Handling and Stability: By replacing the factory rubber bushings with high-performance polyurethane, the rear sway bar becomes more effective at reducing body roll during cornering. This leads to improved vehicle stability, better grip, and sharper handling, particularly during spirited driving or on winding roads.
  • High-Quality Polyurethane Construction: Made from durable polyurethane, these bushings offer significant advantages over the original rubber bushings. They are resistant to wear, heat, and contaminants such as oil and grime, which ensures they maintain their performance and shape over a longer period.
  • Enhanced Performance Without Sacrificing Comfort: While these bushings provide firmer support for the sway bar, they are designed to strike a balance between performance and comfort. This allows you to enjoy improved handling without experiencing a harsh ride, making them suitable for daily driving as well as performance-oriented use.
  • Increased Durability: The polyurethane material ensures longevity and reduces the frequency of bushing replacements, making this a low-maintenance upgrade that keeps your suspension in optimal condition for a longer time.

These 15 mm Rear Sway Bar Bushings are ideal for BMW enthusiasts looking to upgrade their car’s handling dynamics. Whether you're driving a classic BMW like the E24 or a modern model like the E46, these bushings provide a straightforward way to enhance your vehicle's suspension, offering improved cornering precision and reduced body roll, while still preserving ride comfort for everyday use.

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:

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

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.

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.
