by

The Subaru WRX, particularly the GD generation, is a beloved vehicle among car enthusiasts due to its rally heritage and performance capabilities. However, many owners seek to enhance the handling of their WRX for improved driving dynamics. This guide will focus on upgrading struts, sway bars, and bushings to achieve better performance and handling.

Understanding the Importance of Suspension Upgrades

Upgrading your WRX’s suspension components can significantly improve handling, ride quality, and overall driving experience. The stock components are designed for a balance of comfort and performance, but enthusiasts often desire a more aggressive setup. Here are the key benefits of upgrading:

  • Improved Handling: Better control during cornering and braking.
  • Enhanced Stability: Reduced body roll and improved traction.
  • Customizability: Tailor the suspension to your driving style and conditions.

Upgrading Struts

Struts are a critical part of the suspension system, providing support and damping to the vehicle. Upgrading to performance struts can drastically enhance your WRX’s handling characteristics. Here are some considerations:

  • Choose the Right Type: Options include coilovers, adjustable struts, and performance struts.
  • Spring Rates: Consider stiffer spring rates for better handling but be mindful of ride comfort.
  • Installation: Proper installation is crucial; consider professional help if unsure.

Several brands offer high-quality strut upgrades for the GD WRX. Some popular options include:

  • Bilstein B8 Performance Struts
  • KW Variant 1 Coilovers
  • Tein Flex Z Coilovers

Upgrading Sway Bars

Sway bars, also known as anti-roll bars, play a significant role in reducing body roll during cornering. Upgrading these components can lead to sharper handling and improved stability. Consider the following:

  • Thickness: Thicker sway bars increase stiffness and reduce body roll.
  • Adjustability: Adjustable sway bars allow for tuning based on driving preferences.
  • Material: Look for high-quality materials like tubular steel for durability.

Here are some recommended sway bar upgrades for the GD WRX:

  • Whiteline Sway Bars
  • ST Suspensions Sway Bars
  • H&R Sway Bars

Upgrading Bushings

Bushings are often overlooked but are crucial for maintaining proper alignment and handling. Upgrading to stiffer, performance-oriented bushings can improve responsiveness and reduce unwanted movement. Consider these points:

  • Material: Polyurethane bushings are stiffer and provide better feedback compared to rubber.
  • Location: Focus on key areas such as control arms, sway bar links, and subframe mounts.
  • Installation: Some bushings may require special tools for installation.

Consider the following brands for high-quality bushing upgrades:

  • Whiteline Polyurethane Bushings
  • Energy Suspension Bushings
  • SuperPro Bushings

Conclusion

Upgrading the struts, sway bars, and bushings on your GD WRX can lead to a significant improvement in handling and driving enjoyment. Each component plays a vital role in the overall performance of the vehicle. By selecting the right upgrades and ensuring proper installation, you can transform your WRX into a more responsive and enjoyable driving machine.
