The BMW E39 M5 is well-known for its powerful V8 engine and exceptional driving dynamics. However, many enthusiasts seek to enhance its performance further, particularly in terms of traction and handling on the track. One of the most effective upgrades for achieving this is the differential. In this article, we will explore the benefits of upgrading the E39 M5 differential and how it can significantly improve your driving experience.
Understanding the Differential
The differential is a crucial component of any vehicle’s drivetrain. It allows the wheels to rotate at different speeds, especially during turns, while transferring power from the engine. In high-performance vehicles like the E39 M5, the differential plays a vital role in optimizing traction and handling.
Why Upgrade the Differential?
Upgrading the differential can provide several advantages for track enthusiasts:
- Improved Traction: A better differential can distribute power more effectively to the wheels, reducing wheel spin and enhancing grip on the track.
- Enhanced Cornering: Upgraded differentials can help maintain stability during cornering, allowing for faster lap times.
- Better Power Delivery: A performance differential can provide a more responsive feel, improving acceleration out of corners.
Types of Differentials for the E39 M5
When considering a differential upgrade for the E39 M5, there are several types to choose from:
- Open Differential: The stock differential, which provides basic functionality but can lead to traction issues in high-performance situations.
- Limited-Slip Differential (LSD): Offers improved traction by allowing some wheel slip while still providing power to both wheels. Ideal for track use.
- Torque Vectoring Differential: An advanced option that can actively control the distribution of power between the wheels for optimal performance.
Choosing the Right Differential
When selecting a differential for your E39 M5, consider the following factors:
- Driving Style: Determine how you plan to use your vehicle—track days, street driving, or a combination of both.
- Budget: Performance differentials can vary significantly in price, so it’s essential to choose one that fits your budget.
- Installation: Some differentials may require professional installation, which can add to the overall cost.
Installation Process
Upgrading the differential in your E39 M5 is a complex process that typically involves several steps:
- Preparation: Gather all necessary tools and parts, including the new differential and any required fluids.
- Remove the Old Differential: Safely lift the vehicle and remove the existing differential from the rear axle.
- Install the New Differential: Carefully install the new differential, ensuring all connections are secure and properly aligned.
- Fluid Replacement: Fill the new differential with the appropriate fluid to ensure optimal performance.
- Testing: After installation, conduct a thorough test drive to ensure everything is functioning correctly.
Benefits of a Performance Differential
Upgrading to a performance differential can transform the driving experience of your E39 M5:
- Increased Confidence: With better traction and handling, drivers can push their limits with increased confidence.
- Faster Lap Times: Improved power delivery and cornering capabilities can lead to significantly faster lap times on the track.
- Enhanced Driving Enjoyment: The overall driving experience becomes more engaging and enjoyable, making every track day memorable.
Conclusion
Upgrading the differential in your E39 M5 is a worthwhile investment for any track enthusiast. With improved traction, enhanced handling, and a more responsive driving experience, a performance differential can elevate your driving to new heights. Whether you choose a limited-slip or torque vectoring differential, the benefits are undeniable. Take your E39 M5 to the next level and enjoy the thrill of the track like never before.
