The BMW E60 M5 is a remarkable performance vehicle, known for its powerful V10 engine and dynamic handling. However, one area that can significantly enhance its cornering capabilities is the differential. Upgrading the differential to include lockers and limited-slip differentials (LSDs) can transform the driving experience, allowing for better traction and stability during aggressive cornering.
Understanding Differentials
A differential is a crucial component in any vehicle, allowing the wheels to rotate at different speeds, especially during turns. This is essential for maintaining control and stability. In performance cars like the E60 M5, the type of differential can greatly affect handling characteristics.
Types of Differentials
- Open Differential: Provides no torque biasing, allowing wheels to spin independently.
- Limited-Slip Differential (LSD): Transfers torque to the wheel with more traction, improving grip.
- Locking Differential: Locks both wheels together for maximum traction in low-grip situations.
Benefits of Upgrading to LSD
Upgrading to a limited-slip differential offers several advantages, particularly for performance driving. Here are some key benefits:
- Improved Traction: LSDs provide better traction during acceleration out of corners.
- Enhanced Stability: Reduces the likelihood of wheel spin, resulting in more stable handling.
- Better Cornering Performance: Allows for tighter cornering by distributing power effectively.
Choosing the Right LSD for the E60 M5
When selecting an LSD for the E60 M5, consider the following factors:
- Type of LSD: Choose between clutch-type, helical, or viscous LSDs based on your driving style.
- Gear Ratio: Ensure compatibility with your existing gear ratios for optimal performance.
- Adjustability: Some LSDs offer adjustable settings for fine-tuning performance.
Lockers vs. LSDs: Which is Better?
While both lockers and LSDs serve to improve traction, they do so in different ways. Understanding the distinctions can help you make an informed decision:
- Locking Differentials: Provide maximum traction by locking both wheels together, ideal for off-road or extreme conditions.
- LSDs: Offer a balance between everyday drivability and performance, suitable for track use and spirited driving.
Installation Considerations
Installing an upgraded differential can be complex and may require professional assistance. Here are some considerations:
- Professional Installation: Hiring a professional ensures proper setup and alignment.
- Compatibility: Verify that the differential is compatible with your specific E60 M5 model.
- Break-In Period: Allow for a break-in period to ensure optimal performance and longevity.
Maintenance of Upgraded Differentials
To keep your upgraded differential functioning optimally, regular maintenance is essential. Here are some tips:
- Fluid Changes: Regularly change differential fluid to prevent wear and overheating.
- Inspection: Periodically inspect for leaks or unusual noises that may indicate issues.
- Adjustments: Make adjustments as necessary based on driving conditions and performance needs.
Conclusion
Upgrading the differential on your E60 M5 to include lockers or LSDs can significantly enhance your driving experience. By improving traction and cornering performance, you can unlock the full potential of this remarkable vehicle. Consider your driving style, the type of differential that best suits your needs, and ensure proper installation and maintenance for optimal results.
