BMW Sway Bar Kits for BMW Z Series E85/6 (2003-2008)

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.

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.

    The BMW Z4 / E60 / E61 / E39 Front Sway Bar Bushings (25mm) are essential components designed to enhance the suspension performance of various BMW models, including the Z4, E60, E61, and E39. These bushings are critical for connecting the front sway bar to the chassis, helping to improve handling and stability during driving.

    Key Features:

    1. Specifically for 25mm Sway Bars:

      • These bushings are designed for vehicles equipped with a 25mm front sway bar, ensuring a perfect fit for optimal performance and effective control of body roll.
    2. Functionality:

      • The sway bar bushings serve to connect the sway bar to the vehicle's chassis, allowing it to effectively minimize body roll when cornering. This results in improved stability and handling, enhancing the overall driving experience.
    3. Material Options:

      • Available in rubber and polyurethane:
        • Rubber bushings provide excellent noise dampening and a comfortable ride but may wear out more quickly under heavy stress.
        • Polyurethane bushings are known for their durability and performance benefits, offering reduced flex and improved handling, making them a favored choice for performance-oriented drivers.
    4. Improved Handling Characteristics:

      • Replacing worn or degraded bushings with new ones can lead to noticeable improvements in the vehicle's handling dynamics, resulting in more responsive steering and enhanced control during spirited driving.
    5. Wide Compatibility:

      • These bushings are designed to fit a variety of BMW models, including the Z4, E60, E61, and E39, making them an excellent choice for owners looking to maintain or enhance their vehicle’s performance.
    6. Installation:

      • The installation process typically involves detaching the sway bar from the suspension system. While experienced DIY enthusiasts may tackle this project, professional installation is often recommended to ensure proper alignment and performance.

    Benefits of Replacement or Upgrade:

    • Enhanced Cornering Stability: New bushings significantly improve the sway bar's effectiveness, reducing body roll and enhancing cornering stability.
    • Increased Steering Precision: Fresh bushings provide better feedback from the suspension system, resulting in a more connected driving experience.
    • Long-lasting Performance: Upgrading to polyurethane options can increase the lifespan of the sway bar components, minimizing the frequency of replacements.

    In summary, the BMW Z4 / E60 / E61 / E39 Front Sway Bar Bushings (25mm) are critical for maintaining and enhancing the handling and performance of these BMW models. Whether you are replacing worn-out bushings or upgrading to polyurethane for improved durability and responsiveness, ensuring these components are in top condition is vital for enjoying the exceptional driving dynamics associated with BMW vehicles.
