The E39 M5 is a high-performance vehicle renowned for its powerful engine and exceptional handling. However, to fully harness the potential of this iconic car, upgrades to the transmission and differential can significantly enhance power delivery and overall driving experience. In this article, we will explore various upgrades that can be made to the E39 M5’s transmission and differential, focusing on the benefits they bring to performance and handling.
Understanding the E39 M5 Transmission
The E39 M5 features a 6-speed Getrag transmission, which is known for its precision and durability. However, for enthusiasts looking to extract maximum performance, there are several upgrades available that can improve shift speed, enhance reliability, and optimize power transfer.
Transmission Upgrades
- Short Shifter Kit: Installing a short shifter kit reduces the throw distance between gears, allowing for quicker shifts and a more engaging driving experience.
- Performance Clutch: Upgrading to a performance clutch increases grip and reduces slippage, ensuring that power is effectively transferred from the engine to the wheels.
- Transmission Fluid Upgrade: Using high-performance transmission fluid can improve lubrication, reduce heat, and enhance shifting performance.
These upgrades not only improve the responsiveness of the transmission but also contribute to a more enjoyable driving experience on both the road and the track.
The Importance of the Differential
The differential plays a crucial role in how power is distributed to the wheels. The E39 M5 comes equipped with a limited-slip differential (LSD), which helps to improve traction during acceleration and cornering. However, upgrading the differential can further enhance the vehicle’s performance.
Differential Upgrades
- Upgraded Limited-Slip Differential: A higher-performance LSD can provide better torque distribution, improving grip and stability during aggressive driving.
- Differential Bushings: Upgrading to stiffer differential bushings can reduce movement and improve power transfer, resulting in more precise handling.
- Gear Ratio Change: Altering the gear ratio can optimize acceleration and top speed, tailoring the vehicle’s performance to specific driving conditions or preferences.
These differential upgrades can significantly enhance the E39 M5’s handling characteristics, making it more responsive and fun to drive, especially in challenging driving conditions.
Combining Transmission and Differential Upgrades
While upgrading the transmission and differential separately can yield noticeable improvements, combining these upgrades can lead to even greater enhancements in performance. A well-matched transmission and differential setup can optimize power delivery, improve acceleration, and enhance overall handling.
Benefits of Combined Upgrades
- Improved Acceleration: With better power transfer and traction, the vehicle can accelerate more quickly and efficiently.
- Enhanced Cornering Stability: A properly tuned differential and transmission work together to provide better control during turns.
- Increased Driver Engagement: Upgrades that enhance feedback and responsiveness create a more thrilling driving experience.
By investing in both transmission and differential upgrades, E39 M5 owners can unlock the full potential of their vehicle, making it a true performance machine.
Conclusion
The E39 M5 is already an impressive vehicle, but with the right transmission and differential upgrades, it can become even more exhilarating to drive. Whether you are a track enthusiast or simply enjoy spirited driving on the road, these upgrades can enhance power delivery, improve handling, and provide a more engaging experience behind the wheel. Consider these upgrades to elevate your E39 M5 to new heights of performance.
