Track-ready Wrx E85 Conversion: Suspension, Tires, and Power Mods for 1-minute Laps

by

The Subaru WRX is a popular choice among car enthusiasts, especially those looking to enhance their vehicle for track performance. With the right modifications, particularly an E85 conversion, you can significantly boost power and handling, enabling you to achieve impressive lap times. In this article, we will explore essential upgrades for suspension, tires, and power to help you achieve 1-minute laps on the track.

Suspension Upgrades

Suspension is crucial for track performance, as it directly affects handling and stability. Upgrading your WRX’s suspension will enhance cornering capabilities and provide better feedback from the road.

  • Coilover Kits: Investing in a quality coilover kit allows for adjustable ride height and damping settings, enabling you to fine-tune your suspension for different track conditions.
  • Sway Bars: Upgrading to stiffer sway bars can reduce body roll during cornering, improving overall handling and responsiveness.
  • Strut Braces: Adding front and rear strut braces will increase chassis rigidity, enhancing stability during high-speed maneuvers.
  • Camber Kits: Adjustable camber kits allow for precise alignment adjustments, optimizing tire contact with the road during turns.

Tire Selection

Choosing the right tires is vital for maximizing grip and performance on the track. Tires designed for high performance will provide better traction and handling characteristics.

  • Performance Summer Tires: These tires are optimized for warm conditions and provide excellent grip on dry surfaces, making them ideal for track days.
  • Track-Specific Tires: If you frequently participate in track events, consider investing in dedicated track tires that offer superior grip and heat resistance.
  • Tire Pressure Management: Proper tire pressure is essential for performance. Adjust your tire pressure based on track conditions to optimize grip and handling.

Power Modifications

To achieve significant power gains, especially with an E85 conversion, several modifications can be made to your WRX. These upgrades will not only increase horsepower but also improve throttle response.

  • E85 Conversion: Switching to E85 fuel can increase your WRX’s power output due to its higher octane rating and cooling properties. Make sure to tune your engine to handle the new fuel.
  • Cold Air Intake: A high-flow cold air intake system allows for better airflow to the engine, improving combustion efficiency and power.
  • Upgraded Intercooler: A larger intercooler helps maintain lower intake temperatures, which is crucial for performance, especially when using E85.
  • Tune Your ECU: After making significant power modifications, a custom ECU tune is essential to optimize the engine’s performance and ensure reliability.

Final Thoughts

Upgrading your Subaru WRX for track performance involves a combination of suspension, tires, and power modifications. By focusing on these key areas, you can transform your WRX into a track-ready machine capable of achieving 1-minute laps. Always remember to test your modifications in a safe environment and consider professional assistance for installation and tuning.
