For enthusiasts looking to enhance the performance of their Subaru WRX on the track, upgrading the suspension system is one of the most effective modifications. This article will explore the critical components of a handling suspension upgrade, focusing on struts, sway bars, and bushings.
Understanding Suspension Components
The suspension system of a vehicle plays a vital role in handling, comfort, and overall performance. In the context of track days, the right upgrades can significantly improve your WRX’s responsiveness and stability.
Struts
Struts are a crucial part of the suspension system, serving as both shock absorbers and structural components of the vehicle’s suspension. Upgrading struts can lead to improved handling and ride quality.
- Improved dampening control
- Increased stiffness for better cornering
- Adjustable options for customization
When selecting struts for your WRX, consider options that are designed for performance driving. Look for features such as adjustable damping, which allows you to fine-tune the suspension setup based on track conditions.
Sway Bars
Sway bars, also known as anti-roll bars, help reduce body roll during cornering. Upgrading to stiffer sway bars can enhance your WRX’s handling by keeping the car flatter in turns.
- Reduces body roll
- Improves cornering stability
- Enhances overall grip
When considering sway bar upgrades, it’s essential to balance front and rear stiffness. A well-matched setup will provide optimal handling without compromising ride quality.
Bushings
Bushings are rubber or polyurethane components that provide cushioning between various suspension parts. Upgrading bushings can improve responsiveness and reduce unwanted movement in the suspension system.
- Enhances steering response
- Reduces deflection under load
- Increases durability
Polyurethane bushings are a popular choice for performance applications due to their increased stiffness compared to stock rubber bushings. This upgrade can significantly enhance the feel of your WRX on the track.
Choosing the Right Components
When upgrading your WRX’s suspension, it’s crucial to consider how each component works together. A well-rounded setup will provide the best performance on track days.
Compatibility
Ensure that all components you choose are compatible with your WRX model year and trim. Some parts may require additional modifications or adjustments to fit correctly.
Budget Considerations
Suspension upgrades can vary significantly in price. It’s essential to set a budget before starting your upgrade journey. Prioritize components based on your performance goals and driving style.
Installation Options
Decide whether you will be installing the components yourself or seeking professional help. Proper installation is critical to ensure safety and performance.
Conclusion
Upgrading the suspension of your VA WRX is a rewarding investment for track enthusiasts. By carefully selecting struts, sway bars, and bushings, you can transform your vehicle’s handling and performance. Always remember to test your setup and make adjustments as needed for optimal results.
