The BMW E90 M3 is celebrated for its performance, but enthusiasts often seek ways to enhance its handling capabilities further. One of the most effective upgrades is the installation of coilovers, which allow for adjustable ride height and damping settings. This article delves into the benefits of coilover upgrades for the E90 M3, focusing on lowering and stiffening the suspension for improved handling.
Understanding Coilovers
Coilovers are a type of suspension system that combines a shock absorber and a coil spring into a single unit. They offer adjustable height and damping, making them a popular choice for performance enthusiasts. The E90 M3 can greatly benefit from coilover upgrades, allowing drivers to tailor their suspension setup to their driving style and preferences.
Benefits of Lowering the E90 M3
Lowering the ride height of the E90 M3 can lead to several performance benefits:
- Improved Center of Gravity: Lowering the vehicle reduces its center of gravity, enhancing stability during cornering.
- Better Aerodynamics: A lower ride height can improve airflow around the vehicle, reducing drag and increasing performance.
- Enhanced Aesthetics: Many enthusiasts prefer the aggressive stance that comes with a lowered suspension.
Choosing the Right Coilovers
When selecting coilovers for the E90 M3, consider the following factors:
- Adjustability: Look for coilovers that offer adjustable ride height and damping settings.
- Build Quality: Opt for reputable brands known for their durability and performance.
- Intended Use: Determine whether the coilovers will be used for daily driving, track days, or a combination of both.
Stiffening the Suspension
In addition to lowering, stiffening the suspension is crucial for enhancing handling. Stiffer coilovers can reduce body roll and improve responsiveness during cornering.
Impact of Stiff Suspension on Handling
A stiffer suspension setup provides several advantages:
- Reduced Body Roll: Stiffer springs help keep the car level during turns, improving cornering performance.
- Enhanced Feedback: A stiffer setup allows drivers to feel more connected to the road, enhancing overall driving experience.
- Improved Traction: Stiff suspension can help maintain tire contact with the road, leading to better grip.
Installation Tips
Installing coilovers on the E90 M3 can be a rewarding project. Here are some tips to ensure a successful installation:
- Gather the Right Tools: Ensure you have all necessary tools, including a jack, jack stands, and a torque wrench.
- Follow Manufacturer Instructions: Always refer to the specific instructions provided by the coilover manufacturer.
- Consider Professional Help: If you’re unsure about the installation process, consider hiring a professional to ensure optimal setup.
Setting Up Your Coilovers
Once installed, setting up your coilovers correctly is essential for achieving the desired handling characteristics. Here are some steps to follow:
- Adjust Ride Height: Start by adjusting the ride height to your preferred level, keeping in mind the balance between aesthetics and performance.
- Tune Damping Settings: Experiment with different damping settings to find the right balance between comfort and performance.
- Alignment: After installation, ensure your vehicle is properly aligned to avoid uneven tire wear and maintain handling performance.
Conclusion
Upgrading to coilovers on the E90 M3 can significantly enhance its handling capabilities. By lowering and stiffening the suspension, drivers can enjoy improved performance, stability, and feedback. With the right setup, the E90 M3 can become an even more exhilarating driving experience.
