The Subaru WRX has long been a favorite among automotive enthusiasts, particularly for its performance on the track. The VA (2015-2021) generation of the WRX offers a great platform for modifications aimed at enhancing track performance. In this article, we will explore essential upgrades focusing on brakes, suspension, and power to optimize your WRX for circuit days.
Upgrading Brakes for Track Performance
Braking is crucial on the track, where high speeds and sharp turns demand reliable stopping power. Upgrading your WRX’s braking system not only enhances performance but also boosts safety. Here are key modifications to consider:
- Performance Brake Pads: Invest in high-friction brake pads designed for track use. They provide better bite and fade resistance under heavy braking conditions.
- Aftermarket Brake Rotors: Consider slotted or drilled rotors for improved heat dissipation and reduced brake fade.
- Stainless Steel Brake Lines: Upgrade to stainless steel lines to enhance pedal feel and reduce expansion under pressure.
- Brake Fluid: Use high-temperature brake fluid to prevent boiling during intense track sessions.
Enhancing Suspension for Better Handling
A well-tuned suspension is vital for achieving optimal handling and stability on the track. Here are several modifications that can significantly improve your WRX’s suspension setup:
- Coilover Kits: Installing adjustable coilovers allows you to fine-tune ride height and damping settings to suit track conditions.
- Anti-Roll Bars: Upgrading to stiffer anti-roll bars can reduce body roll and enhance cornering performance.
- Strut Braces: Adding strut braces can improve chassis rigidity, leading to better handling characteristics.
- Camber Plates: Adjustable camber plates enable you to optimize tire contact during cornering for improved grip.
Boosting Power for Track Days
To fully exploit the potential of your upgraded brakes and suspension, enhancing the power output of your WRX is essential. Here are some effective modifications to consider:
- ECU Tuning: A performance tune can unlock additional horsepower and torque, optimizing engine performance for track use.
- Upgraded Turbocharger: Consider a larger turbocharger for increased airflow and power. Ensure supporting mods are in place for reliability.
- High-Performance Exhaust System: An aftermarket exhaust can improve airflow, reduce back pressure, and enhance sound.
- Cold Air Intake: Installing a high-flow cold air intake can increase engine efficiency and power by improving airflow.
Conclusion
Upgrading your VA WRX for track days involves thoughtful modifications to the brakes, suspension, and powertrain. By focusing on these key areas, you can significantly enhance your vehicle’s performance and enjoy a more exhilarating track experience. Whether you’re a seasoned racer or a weekend enthusiast, these upgrades will help you get the most out of your Subaru WRX.
