The Subaru WRX is known for its impressive performance, but for those looking to take it to the next level, particularly for track use, modifications are essential. This article will explore handling modifications specifically for an E85 conversion, focusing on strut braces, wide tires, and suspension tuning.
Understanding E85 Conversion
E85 is a blend of 85% ethanol and 15% gasoline, offering higher octane levels and better performance. However, converting your WRX to run on E85 requires specific modifications to maximize efficiency and power.
Benefits of E85
- Higher octane rating allows for more aggressive tuning.
- Potential for increased horsepower and torque.
- Lower fuel costs in some regions.
Challenges of E85
- Requires larger fuel injectors and upgraded fuel pump.
- Can lead to increased fuel consumption.
- Potential for corrosion in fuel system components.
Strut Braces: Enhancing Chassis Rigidity
One of the key modifications for improving handling on the track is the installation of strut braces. These components connect the strut towers, providing additional stiffness to the chassis.
Types of Strut Braces
- Front strut braces: Improve steering response and cornering stability.
- Rear strut braces: Enhance rear-end grip and balance.
- Cross braces: Provide additional support between the front and rear suspension.
Installation Tips
When installing strut braces, ensure proper alignment and torque settings to avoid any issues. Consider a professional installation for optimal results.
Wide Tires: Maximizing Grip
Upgrading to wider tires is a crucial step in enhancing your WRX’s handling capabilities. Wider tires provide a larger contact patch, improving grip during acceleration, braking, and cornering.
Choosing the Right Tires
- Consider tire width: A wider tire can significantly improve grip.
- Look for performance-oriented tread patterns for better traction.
- Check compatibility with your wheel size and suspension setup.
Tire Pressure Considerations
Proper tire pressure is essential for maximizing performance. Monitor tire pressure regularly and adjust based on track conditions to ensure optimal handling.
Suspension Tuning: Fine-Tuning Handling
Suspension tuning is critical for achieving the desired handling characteristics on the track. Adjustments can be made to dampers, springs, and sway bars to optimize performance.
Adjustable Coilovers
Investing in adjustable coilovers allows for precise tuning of ride height and damping settings. This flexibility is essential for adapting to different track conditions.
Sway Bars and End Links
- Upgrading sway bars can reduce body roll during cornering.
- Adjustable end links allow for fine-tuning sway bar stiffness.
Alignment Settings
After making suspension modifications, proper alignment is crucial. Adjust camber, caster, and toe settings to enhance tire contact and handling dynamics.
Final Considerations
Modifying your WRX for track readiness, especially with an E85 conversion, requires careful consideration of strut braces, tire selection, and suspension tuning. Each component plays a vital role in enhancing performance and ensuring safety on the track.
Regular Maintenance
Keep in mind that regular maintenance is essential to ensure the longevity of your modifications. Inspect components frequently and replace any worn parts to maintain optimal performance.
Track Testing
Finally, always test your vehicle on the track after making modifications. This will help you understand how your changes affect handling and performance, allowing for further fine-tuning as needed.
