Upgrading the A90 Supra’s Differential and Tires for Improved Traction and Handling

by

The A90 Supra has garnered attention for its impressive performance and sleek design. However, to truly unlock its potential, upgrading the differential and tires can significantly enhance traction and handling. This article will explore the benefits and options available for these upgrades.

Understanding the Importance of Differential Upgrades

The differential plays a crucial role in how power is distributed to the wheels. An upgraded differential can improve cornering, acceleration, and overall performance. Here are some key points to consider:

  • Power Distribution: A better differential allows for more efficient power transfer to the wheels.
  • Cornering Performance: An upgraded differential can enhance grip during turns.
  • Durability: High-performance differentials often use stronger materials, leading to increased longevity.

Types of Differentials to Consider

There are several types of differentials available for the A90 Supra. Each has its own advantages:

  • Open Differential: Standard but can lead to wheel spin in low traction conditions.
  • Limited Slip Differential (LSD): Provides better traction by distributing power to the wheel with more grip.
  • Locking Differential: Locks both wheels together for maximum traction, ideal for off-road conditions.
  • Torque Vectoring Differential: Offers the most advanced performance by adjusting power between wheels based on traction needs.

Choosing the Right Tires for Enhanced Traction

Tires are the only contact point between your vehicle and the road, making them essential for performance. Selecting the right tires can dramatically influence traction and handling. Here are factors to consider:

  • Tire Type: Summer tires offer better grip in warm conditions, while all-season tires provide versatility.
  • Tread Pattern: Tires with aggressive tread patterns can improve grip on various surfaces.
  • Width and Aspect Ratio: Wider tires generally provide better traction but can affect handling.

When upgrading tires for the A90 Supra, consider the following options:

  • Michelin Pilot Sport 4S: Known for excellent grip and handling in both dry and wet conditions.
  • Continental ExtremeContact Sport: Offers a balance of performance and longevity.
  • Bridgestone Potenza RE-71R: A track-focused tire that excels in dry conditions.
  • Goodyear Eagle F1 Supercar 3: Designed for high-performance vehicles with superior grip.

Installation and Considerations

Upgrading the differential and tires requires careful consideration and installation. Here are some important points to keep in mind:

  • Professional Installation: It’s recommended to have these upgrades installed by professionals to ensure safety and performance.
  • Alignment: After tire upgrades, a wheel alignment is crucial to maintain handling and tire life.
  • Break-in Period: New tires and differentials may require a break-in period to achieve optimal performance.

Conclusion

Upgrading the differential and tires on the A90 Supra can significantly enhance its performance, providing better traction and handling. By understanding the options available and considering professional installation, drivers can maximize their driving experience. Whether on the track or the road, these upgrades are essential for unlocking the full potential of the A90 Supra.
