Track-ready M4 Competition Mods: Upgrading Differential and Chassis Components

by

The BMW M4 Competition is a high-performance vehicle that excels on the track, but there’s always room for improvement. Upgrading the differential and chassis components can significantly enhance performance, handling, and overall driving experience. In this article, we’ll explore various modifications that can take your M4 Competition to the next level.

Why Upgrade Differential and Chassis Components?

Upgrading the differential and chassis components of your M4 Competition can lead to better traction, improved cornering stability, and enhanced overall performance. Here are some key reasons to consider these upgrades:

  • Improved Traction: A better differential can distribute power more effectively to the wheels, reducing wheel spin.
  • Enhanced Handling: Upgraded chassis components can lead to better stability during high-speed maneuvers.
  • Increased Durability: Performance parts are often built to withstand the rigors of track use, enhancing the longevity of your vehicle.

Upgrading the Differential

The differential plays a crucial role in how power is distributed to the wheels. Upgrading to a performance differential can provide several benefits:

  • Limited Slip Differential (LSD): An LSD helps to improve traction by allowing for differences in wheel speed while still providing power to both wheels.
  • Adjustable Differential Settings: Some aftermarket differentials allow for tuning, enabling drivers to adjust settings based on track conditions.
  • Durability: Performance differentials are often built with stronger materials, making them more reliable under extreme conditions.

Here are some popular differential upgrades for the M4 Competition:

  • Wavetrac LSD: Known for its superior performance in both wet and dry conditions.
  • OS Giken Super Lock LSD: Offers excellent traction and stability during cornering.
  • Quaife ATB Differential: Provides seamless power delivery and improved handling characteristics.

Chassis Component Upgrades

Upgrading chassis components can dramatically affect handling and ride quality. Key areas to focus on include suspension, sway bars, and bushings.

Suspension Upgrades

The suspension system is vital for maintaining contact with the road. Upgrading to a performance suspension can improve handling and comfort:

  • Coilovers: Adjustable coilover kits allow for customization of ride height and damping settings.
  • Performance Shocks: Upgrading shocks can improve response and reduce body roll during cornering.
  • Sway Bars: Thicker sway bars can reduce body roll and improve cornering stability.

Consider these popular suspension upgrades for your M4 Competition:

  • BC Racing Coilovers: Offers a great balance between performance and comfort.
  • H&R Sway Bars: Known for their rigidity and effectiveness in reducing body roll.
  • KW Variant 3 Coilovers: Provides adjustable compression and rebound settings for optimal performance.

Benefits of Upgrading Chassis Components

Upgrading chassis components not only enhances performance but also improves driver confidence and safety. Here are some benefits:

  • Better Cornering: Improved chassis components lead to more precise handling in corners.
  • Increased Feedback: Performance parts provide better road feedback, allowing for more informed driving decisions.
  • Enhanced Stability: Upgraded components can reduce the likelihood of oversteer or understeer.

Conclusion

Upgrading the differential and chassis components of your BMW M4 Competition can significantly enhance its track performance. By investing in quality parts, you can achieve improved traction, handling, and overall driving experience. Whether you’re a seasoned track enthusiast or a casual driver looking to improve your M4, these upgrades can help you unlock the full potential of your vehicle.
