E39 M5 Track Performance Mods: Coilovers, Brakes, and Aero for Aggressive Driving

by

The BMW E39 M5 is a legendary performance sedan that has captured the hearts of enthusiasts for decades. For those looking to enhance its track performance, modifications can significantly improve handling, braking, and aerodynamics. In this article, we will explore key modifications including coilovers, brakes, and aerodynamic enhancements that can transform your E39 M5 into a track-ready beast.

Coilovers: Lowering and Improving Handling

Coilovers are one of the most impactful modifications you can make to your E39 M5. They allow for adjustable ride height and damping settings, enabling you to tailor the suspension to your driving style and track conditions.

  • Adjustable Ride Height: Lowering the car lowers the center of gravity, which enhances stability during high-speed cornering.
  • Improved Damping: Adjustable damping settings allow you to fine-tune the suspension for both comfort on the street and performance on the track.
  • Increased Stiffness: Stiffer springs can reduce body roll, providing better handling characteristics.
  • KW Variant 3
  • BC Racing BR Series
  • H&R Street Performance

Each of these options offers a unique set of features and benefits. Researching and selecting the right coilover system can greatly enhance your E39 M5’s track capabilities.

Brakes: Stopping Power for Track Days

Upgrading the braking system is essential for any performance vehicle, especially for track driving. The E39 M5 comes equipped with solid brakes, but for aggressive driving, enhancements can make a significant difference.

  • Performance Brake Pads: Upgrading to high-friction pads can improve stopping power and reduce brake fade during extended use.
  • Slotted or Drilled Rotors: These rotors help dissipate heat and improve braking performance under heavy use.
  • Stainless Steel Brake Lines: These lines provide a firmer pedal feel and reduce the chance of brake line expansion under pressure.
  • Brembo GT Brake Kit
  • StopTech Sport Brake Pads
  • ATE PowerDisc Rotors

Investing in a quality brake system is crucial for maintaining control and safety while pushing the limits of your E39 M5 on the track.

Aero Enhancements: Cutting Through the Air

Aerodynamic modifications can significantly improve the stability and handling of your E39 M5 at high speeds. By reducing drag and increasing downforce, you can enhance the car’s performance on the track.

  • Front Splitter: A front splitter increases downforce on the front end, improving grip during cornering.
  • Rear Spoiler: A properly designed rear spoiler can help balance the car’s aerodynamics and reduce lift.
  • Side Skirts: These help manage airflow along the sides of the vehicle, reducing drag and improving stability.
  • Vorsteiner Aero Kit
  • AC Schnitzer Body Kit
  • BMW M Performance Parts

Choosing the right aerodynamic enhancements can make a noticeable difference in your E39 M5’s performance on the track, allowing for greater confidence and speed.

Conclusion

Modifying your E39 M5 for track performance involves careful consideration of various components, including coilovers, brakes, and aero enhancements. Each modification contributes to a more aggressive driving experience and improved lap times. By investing in quality parts and tuning your setup, you can unlock the full potential of this remarkable performance sedan.
