The E39 M5, known for its performance and luxury, can be further enhanced by upgrading its differential and driveshaft. These modifications not only improve power transfer but also enhance the overall durability of the vehicle. In this article, we will explore the benefits of upgrading these components and guide you through the process.
Understanding the Importance of Differential and Driveshaft Upgrades
The differential and driveshaft play crucial roles in the power delivery system of the E39 M5. Upgrading these components can lead to significant improvements in performance. Here are some key reasons to consider these upgrades:
- Improved Power Transfer: Upgraded differentials provide better torque distribution, allowing for more efficient power transfer to the wheels.
- Enhanced Durability: High-performance driveshafts are designed to withstand higher stresses, reducing the risk of failure during aggressive driving.
- Better Handling: An upgraded differential can improve traction and stability, especially during cornering.
- Increased Performance: Overall vehicle performance is enhanced, leading to quicker acceleration and better responsiveness.
Choosing the Right Differential for the E39 M5
When selecting a differential for your E39 M5, consider the following options:
- Limited Slip Differential (LSD): Provides better traction by distributing power to the wheels with the most grip.
- Gear Ratio Options: Choosing a different gear ratio can enhance acceleration or top speed, depending on your driving style.
- Aftermarket Brands: Brands like Quaife and Wavetrac offer high-quality LSDs specifically designed for performance applications.
Installation Process for Differential Upgrade
Upgrading the differential requires careful installation. Here are the general steps involved:
- Preparation: Gather necessary tools and parts, including the new differential, seals, and fluids.
- Remove the Old Differential: Lift the car and remove the driveshaft, then unbolt the differential from its housing.
- Install the New Differential: Position the new differential in place and secure it with bolts.
- Reattach the Driveshaft: Connect the driveshaft back to the new differential.
- Fluid Replacement: Fill the differential with the appropriate fluid as specified by the manufacturer.
Upgrading the Driveshaft for Enhanced Performance
The driveshaft is another critical component that benefits from an upgrade. A performance driveshaft can significantly improve the responsiveness and overall performance of the E39 M5.
- Material Selection: Consider lightweight materials such as carbon fiber or aluminum for reduced weight and improved performance.
- Increased Strength: Upgraded driveshafts are designed to handle higher torque loads, making them ideal for high-performance applications.
- Improved Balance: A well-balanced driveshaft reduces vibrations, leading to a smoother driving experience.
Installation Process for Driveshaft Upgrade
Installing a new driveshaft follows a similar process to the differential upgrade:
- Preparation: Ensure you have the new driveshaft and necessary tools ready for installation.
- Remove the Old Driveshaft: Unbolt the driveshaft from both the transmission and differential ends.
- Install the New Driveshaft: Position the new driveshaft and secure it to both the transmission and differential.
- Check for Proper Alignment: Ensure the driveshaft is aligned correctly to avoid vibrations.
- Test Drive: Take the vehicle for a test drive to ensure everything is functioning smoothly.
Conclusion
Upgrading the differential and driveshaft of the E39 M5 can lead to significant improvements in power transfer, durability, and overall performance. By choosing the right components and following the proper installation procedures, you can enhance your driving experience and maximize the capabilities of this remarkable vehicle.
