The all-wheel-drive (AWD) systems in vehicles like the Subaru WRX and Mitsubishi Lancer Evolution (Evo) have long been celebrated for their performance, especially in challenging driving conditions. However, when it comes to high-speed cornering, upgrading these systems can lead to significant improvements in handling and stability. This article explores various upgrades and modifications that can enhance the AWD systems of the WRX and Evo, providing drivers with a more engaging and controlled experience.
Understanding the Basics of AWD Systems
AWD systems distribute power to all four wheels, enhancing traction and stability. Both the WRX and Evo utilize different AWD technologies, which affect their handling characteristics. Understanding these systems is crucial for identifying potential upgrades.
- Subaru WRX: Symmetrical AWD with a center differential.
- Mitsubishi Evo: Active Center Differential (ACD) for dynamic power distribution.
Key Upgrades for High-Speed Cornering
To improve handling in high-speed corners, several upgrades can be considered. These modifications can enhance the performance of the AWD systems in both the WRX and Evo.
1. Suspension Upgrades
Upgrading the suspension is one of the most effective ways to enhance cornering performance. A stiffer suspension setup can reduce body roll and improve responsiveness.
- Adjustable coilovers for better ride height and damping control.
- Upgraded sway bars to reduce body roll during cornering.
2. Tire Selection
The choice of tires plays a critical role in high-speed cornering. Performance-oriented tires can provide better grip and stability.
- Summer tires designed for optimal grip in dry conditions.
- Performance all-season tires for versatility in various weather conditions.
3. Differential Upgrades
Upgrading the differentials can significantly impact how power is distributed to the wheels, enhancing traction and stability during cornering.
- Limited-slip differentials (LSD) for improved cornering grip.
- Upgraded center differentials for better power distribution.
4. Brake System Enhancements
Effective braking is essential for high-speed cornering. Upgrading the brake system can improve stopping power and reduce brake fade.
- Performance brake pads for better grip and heat resistance.
- Upgraded rotors for improved cooling and braking efficiency.
Performance Tuning and ECU Remapping
Tuning the engine and remapping the ECU can enhance the overall performance of the WRX and Evo, leading to better acceleration and power delivery during cornering.
- ECU remapping for increased horsepower and torque.
- Performance exhaust systems for improved airflow and sound.
Testing and Fine-Tuning
After completing the upgrades, it is essential to test the vehicle’s performance. Fine-tuning the suspension, alignment, and tire pressures can lead to further improvements in handling.
- Track testing to evaluate handling characteristics.
- Adjusting alignment settings for optimal cornering performance.
Conclusion
Upgrading the AWD systems of the Subaru WRX and Mitsubishi Evo can yield significant improvements in handling during high-speed cornering. By focusing on suspension, tires, differentials, brakes, and performance tuning, drivers can enhance their driving experience and achieve better control on the road or track.
