When it comes to enhancing the performance of a built WRX engine, the suspension system plays a crucial role. Upgrading to STi suspension and incorporating upgraded bushings can significantly improve handling and overall driving experience. This article will delve into the benefits of these modifications and how they can transform your WRX.
Understanding the Importance of Suspension
The suspension system is responsible for maintaining tire contact with the road, providing stability, and ensuring comfort during driving. A well-tuned suspension can drastically affect the vehicle’s handling characteristics, especially in performance-oriented cars like the WRX.
Benefits of STi Suspension Swap
Subaru’s STi (Subaru Tecnica International) suspension components are designed for performance and agility. Swapping to STi suspension offers several advantages:
- Improved Handling: STi suspension components are engineered to reduce body roll and enhance cornering stability.
- Lower Ride Height: The STi suspension typically lowers the vehicle’s center of gravity, further improving handling dynamics.
- Enhanced Damping: STi struts and shocks provide better damping characteristics, allowing for more responsive handling.
- Stiffer Springs: The stiffer springs in STi suspension help maintain better tire contact during aggressive maneuvers.
Upgrading Bushings for Improved Performance
Bushings are critical components that connect various suspension parts. Upgrading to performance bushings can further enhance handling. Here’s how:
- Reduced Flex: Upgraded bushings are typically made from stiffer materials, reducing flex and improving response during cornering.
- Increased Durability: Performance bushings are designed to withstand higher loads and stresses, ensuring longevity.
- Better Alignment: Stiffer bushings help maintain alignment under load, improving tire wear and handling precision.
- Enhanced Feedback: Upgraded bushings can provide better road feel, allowing drivers to sense changes in traction and handling.
Choosing the Right Components
When selecting STi suspension components and bushings, consider the following:
- Compatibility: Ensure that the parts are compatible with your specific WRX model and year.
- Intended Use: Choose components based on your driving style, whether it’s daily driving, track use, or rally.
- Brand Reputation: Opt for reputable brands known for quality and performance in the Subaru community.
- Reviews and Recommendations: Look for feedback from other WRX owners who have made similar upgrades.
Installation Process
Installing STi suspension and upgraded bushings can be a rewarding DIY project or a job for a professional mechanic. Here are the general steps involved:
- Gather Necessary Tools: Ensure you have the right tools, including jack stands, wrenches, and a torque wrench.
- Remove Old Suspension Components: Safely lift the vehicle and remove the stock suspension parts.
- Install New STi Components: Follow manufacturer instructions to install the new STi suspension parts.
- Replace Bushings: Remove old bushings and replace them with upgraded ones, ensuring proper alignment.
- Check Alignment: After installation, have the vehicle’s alignment checked and adjusted as necessary.
Testing Your Upgrades
Once the installation is complete, it’s essential to test the upgrades to ensure everything is functioning correctly:
- Initial Drive: Take the car for a short drive to assess handling and comfort.
- Cornering Tests: Test the vehicle’s cornering ability at various speeds to evaluate improvements.
- Feedback and Adjustments: Pay attention to any unusual noises or handling characteristics and make adjustments if necessary.
Conclusion
Upgrading to STi suspension and performance bushings on a built WRX engine can significantly enhance handling, stability, and overall driving enjoyment. By carefully selecting components and following proper installation procedures, drivers can experience the full potential of their WRX. Whether for daily driving or competitive racing, these upgrades are sure to make a noticeable difference.
