by

The BMW E39 M5 is renowned for its performance and handling. To enhance its capabilities further, upgrading components such as the differential, struts, and bushings is essential. This article will guide you through the process of handling these upgrades effectively.

Understanding the Importance of Upgrades

Upgrading the differential, struts, and bushings can significantly improve the handling characteristics of the E39 M5. Each component plays a crucial role in the vehicle’s overall performance.

  • Differential: Enhances power delivery and traction.
  • Struts: Improves ride quality and stability.
  • Bushings: Reduces unwanted movement and increases responsiveness.

Upgrading the Differential

The differential is a key component that affects how power is distributed to the wheels. Upgrading to a limited-slip differential (LSD) can provide better traction and handling during cornering.

  • Benefits of an LSD:
    • Improved traction on slippery surfaces.
    • Better cornering performance.
    • Enhanced acceleration out of turns.
  • Installation Tips:
    • Ensure proper alignment during installation.
    • Use high-quality fluids to maintain performance.
    • Consider professional installation if unsure.

Upgrading the Struts

Struts are vital for maintaining the vehicle’s ride quality and handling. Upgrading to performance struts can greatly enhance the E39 M5’s responsiveness and stability.

  • Types of Struts:
    • Adjustable struts for customizable performance.
    • Coilover systems for lowered stance and improved handling.
  • Installation Considerations:
    • Ensure compatibility with existing suspension components.
    • Check for proper alignment post-installation.

Upgrading the Bushings

Bushings play a crucial role in connecting various suspension components. Upgrading to performance bushings can reduce flex and improve handling precision.

  • Benefits of Performance Bushings:
    • Increased rigidity for better handling.
    • Reduced noise and vibration.
    • Improved steering response.
  • Installation Tips:
    • Use a bushing press for easier installation.
    • Lubricate bushings to reduce friction.
    • Inspect surrounding components for wear.

Conclusion

Upgrading the differential, struts, and bushings on the E39 M5 can significantly enhance its handling and performance. Each component upgrade contributes to a more responsive and enjoyable driving experience. By following the tips and recommendations outlined in this article, you can ensure a successful upgrade process.
