Track-ready Handling: Suspension and Tire Choices for Wrx vs Evo at 1.5g Lateral Grip

by

When it comes to high-performance vehicles, the Subaru WRX and Mitsubishi Lancer Evolution (Evo) have long been contenders in the world of motorsports. Both vehicles are known for their impressive handling capabilities, especially when it comes to achieving high lateral grip on the track. In this article, we will explore the suspension and tire choices for both the WRX and Evo, specifically focusing on their performance at 1.5g lateral grip.

Understanding Lateral Grip

Lateral grip refers to a vehicle’s ability to maintain traction while cornering. Achieving 1.5g of lateral grip is a significant benchmark in motorsport, indicating that the vehicle can sustain forces equal to 1.5 times its weight during a turn. This level of grip requires careful consideration of suspension setup and tire selection.

Suspension Choices

The suspension system plays a crucial role in a car’s handling characteristics. For both the WRX and Evo, the following factors must be considered:

  • Spring Rates: Stiffer springs can improve handling by reducing body roll.
  • Dampers: High-quality dampers help control the motion of the springs and improve grip.
  • Sway Bars: Upgraded sway bars can enhance cornering stability.
  • Alignment Settings: Proper alignment can maximize tire contact with the road.

Subaru WRX Suspension Setup

The WRX typically benefits from a well-balanced all-wheel-drive system, which can be enhanced with specific suspension modifications:

  • Coilover Kits: Adjustable coilovers allow for customization of ride height and damping.
  • Upgraded Bushings: Performance bushings can reduce flex and improve response.
  • Camber Plates: These allow for adjustable camber settings, enhancing tire contact during cornering.

Mitsubishi Lancer Evolution Suspension Setup

The Evo is known for its agile handling, which can be further improved with the right suspension choices:

  • Adjustable Dampers: These can be tuned for specific track conditions, providing a competitive edge.
  • Stiffer Springs: Upgrading to stiffer springs can reduce body roll and improve cornering performance.
  • Rear Sway Bar: A thicker rear sway bar can help balance the car during high-speed turns.

Tire Choices for Optimal Grip

Tires are the only contact between the vehicle and the road, making their selection critical for achieving high lateral grip. The following factors should be considered when choosing tires for both the WRX and Evo:

  • Tire Compound: Softer compounds generally offer better grip but may wear faster.
  • Tread Design: Tires with aggressive tread patterns can enhance cornering performance.
  • Width: Wider tires can provide a larger contact patch, improving grip.
  • Temperature Range: Selecting tires that perform well in the expected temperature range is essential.

For the WRX, several tire options stand out for track use:

  • Michelin Pilot Sport PS2: Known for its balance of grip and durability.
  • Bridgestone Potenza RE71R: Offers exceptional grip and responsiveness.
  • Goodyear Eagle F1 Supercar: A great option for high-performance driving.

The Evo also has a variety of tire choices that can maximize performance:

  • Continental ExtremeContact Sport: Excellent wet and dry grip with a focus on performance.
  • Yokohama ADVAN Neova AD08R: Renowned for its grip and quick response.
  • Dunlop Direzza ZIII: A popular choice among track enthusiasts for its performance capabilities.

Comparing Performance at 1.5g Lateral Grip

Both the Subaru WRX and Mitsubishi Lancer Evolution can achieve impressive performance levels at 1.5g lateral grip. However, their characteristics may differ based on suspension and tire choices:

  • WRX: Typically offers a more balanced feel, making it easier for novice drivers to handle.
  • Evo: Known for its sharp turn-in and agility, appealing to experienced drivers seeking precision.

Conclusion

In conclusion, both the Subaru WRX and Mitsubishi Lancer Evolution are capable of impressive performance at 1.5g lateral grip with the right suspension and tire choices. Understanding the nuances of each vehicle’s setup can help drivers maximize their track performance and enjoy the thrill of high-speed cornering. Whether you prefer the balanced approach of the WRX or the agile precision of the Evo, proper modifications can elevate your driving experience on the track.
