The BMW E46 M3 is renowned for its exceptional performance and driving dynamics. However, enthusiasts often seek ways to enhance its handling further. Upgrading to KW V3 coilovers and polyurethane bushings can significantly improve the M3’s suspension performance, providing a more responsive and engaging driving experience.
Why Upgrade to KW V3 Coilovers?
KW V3 coilovers are a popular choice among E46 M3 owners looking to enhance their vehicle’s handling characteristics. These coilovers offer adjustable ride height and damping, allowing drivers to fine-tune their suspension setup to meet specific driving preferences and conditions.
- Adjustable Damping: KW V3 coilovers feature independent compression and rebound adjustments, enabling precise tuning for various driving scenarios.
- Height Adjustment: The ability to lower the ride height not only improves aesthetics but also lowers the center of gravity, enhancing stability during cornering.
- Improved Handling: The coilovers provide a more direct connection between the road and the driver, resulting in sharper handling and better feedback.
Benefits of Polyurethane Bushings
Polyurethane bushings are another excellent upgrade for the E46 M3. Unlike factory rubber bushings, which can deteriorate over time, polyurethane bushings offer enhanced durability and performance.
- Increased Stiffness: Polyurethane bushings provide a firmer connection between components, reducing unwanted movement and improving responsiveness.
- Longevity: These bushings are resistant to wear and tear, ensuring a longer lifespan compared to traditional rubber bushings.
- Better Alignment: Upgraded bushings help maintain proper alignment under load, which is crucial for optimal handling and tire wear.
Installation Process
Installing KW V3 coilovers and polyurethane bushings on your E46 M3 can be a rewarding project. While some enthusiasts may choose to tackle the installation themselves, it’s advisable to consult a professional for the best results.
Tools Required
- Jack and jack stands
- Socket set
- Wrenches
- Torque wrench

Performance Improvements
Once the KW V3 coilovers and polyurethane bushings are installed, drivers will notice a significant improvement in handling. The car feels more planted during cornering, with reduced body roll and improved traction. The adjustable damping allows drivers to tailor the suspension to their driving style, whether for daily driving or track use.
Conclusion
Upgrading to KW V3 coilovers and polyurethane bushings is an excellent way to enhance the handling of the BMW E46 M3. These modifications not only improve performance but also contribute to a more enjoyable driving experience.
