Differential Upgrades for Track Cars: Achieving Better Cornering and 10+ Hp Gains

by

Upgrading the differential in your track car can lead to significant improvements in handling and performance. A well-chosen differential upgrade not only enhances cornering capabilities but can also provide gains of over 10 horsepower. This article explores the benefits, types, and considerations for differential upgrades in track cars.

Understanding Differentials

The differential is a crucial component in a vehicle’s drivetrain. It allows the wheels to rotate at different speeds, especially during turns. Understanding how differentials work is essential for making informed upgrades.

Types of Differentials

  • Open Differential: Common in most cars, it provides power to the wheel with the least resistance.
  • Limited-Slip Differential (LSD): Offers better traction by distributing power to both wheels.
  • Locking Differential: Locks both wheels together for maximum traction.
  • Torque Vectoring Differential: Distributes torque between wheels for optimal handling.

Benefits of Upgrading Your Differential

Upgrading your differential can yield several performance benefits, especially for track-focused vehicles. Here are some key advantages:

  • Improved Traction: Enhanced grip during acceleration and cornering.
  • Better Cornering: Reduces understeer and oversteer, leading to more predictable handling.
  • Increased Power Delivery: More efficient transfer of power to the wheels, resulting in better acceleration.
  • Enhanced Stability: Provides better control during high-speed maneuvers.

Choosing the Right Differential Upgrade

Selecting the appropriate differential upgrade depends on your specific needs and the type of racing you participate in. Consider the following factors:

  • Driving Style: Choose a differential that complements your driving style, whether aggressive or smooth.
  • Track Conditions: Differentials perform differently under various track conditions, such as wet or dry surfaces.
  • Vehicle Type: Ensure compatibility with your vehicle’s make and model.
  • Budget: Set a budget that includes the cost of the differential and installation.

Here are some popular differential upgrades that track car enthusiasts often consider:

  • Quaife ATB Differential: A popular choice for its smooth operation and increased traction.
  • Wavetrac Differential: Known for its unique design that provides better grip in low-traction situations.
  • OS Giken LSD: Offers adjustable settings for tailored performance on the track.
  • Ford 8.8 Differential: Often used in muscle cars, known for its strength and reliability.

Installation Considerations

Installing a new differential requires careful consideration and expertise. Here are some points to keep in mind:

  • Professional Installation: It’s recommended to have a professional perform the installation to ensure proper setup.
  • Break-In Period: Allow for a break-in period to ensure optimal performance and longevity.
  • Regular Maintenance: Keep up with maintenance to prevent issues and prolong the life of your differential.

Conclusion

Upgrading your differential can significantly enhance your track car’s performance, offering better cornering and power gains. By understanding the types of differentials and their benefits, you can make an informed decision that aligns with your racing goals. Whether you choose a limited-slip or a torque vectoring differential, the right upgrade can transform your driving experience on the track.
