The Subaru WRX has long been celebrated for its performance and handling capabilities. However, enthusiasts and drivers constantly seek ways to enhance these attributes further. One effective method to achieve this is through the improvement of suspension components, specifically the front and rear suspension bushings and anti-roll bars. This article delves into how these modifications can significantly enhance the handling of the GD WRX.
Understanding Suspension Bushings
Suspension bushings are crucial components that connect various parts of the suspension system. They provide cushioning and help absorb shocks from the road, ensuring a smoother ride. However, factory bushings can often be soft and allow excessive movement, leading to less precise handling.
Benefits of Upgrading Suspension Bushings
Upgrading to stiffer, performance-oriented bushings can yield several benefits:
- Improved Steering Response: Stiffer bushings reduce play in the suspension, leading to more direct steering input.
- Enhanced Stability: With less movement, the car remains more stable during cornering, reducing body roll.
- Better Tire Contact: Improved bushings help maintain consistent tire contact with the road, enhancing grip.
Types of Suspension Bushings
There are various types of bushings available for the GD WRX, each offering different levels of performance and comfort:
- OEM Bushings: Original equipment manufacturer bushings provide a comfortable ride but may not offer the best performance.
- Polyurethane Bushings: These provide a stiffer option that enhances handling while still absorbing some road imperfections.
- Solid Bushings: The most performance-oriented choice, solid bushings eliminate any movement but can lead to a harsher ride.
Understanding Anti-Roll Bars
Anti-roll bars, also known as sway bars, are designed to reduce body roll during cornering. They connect the left and right sides of the suspension, helping to distribute weight evenly and improve stability.
Benefits of Upgrading Anti-Roll Bars
Upgrading the anti-roll bars can provide significant handling improvements:
- Reduced Body Roll: Stiffer anti-roll bars minimize body lean during turns, allowing for sharper cornering.
- Improved Cornering Performance: With better weight distribution, the car can maintain higher speeds through corners.
- Enhanced Driver Confidence: A more stable ride leads to increased driver confidence, especially in high-speed situations.
Choosing the Right Anti-Roll Bars
When selecting anti-roll bars for the GD WRX, consider the following factors:
- Diameter: Larger diameter bars provide stiffer performance, but may also lead to a harsher ride.
- Adjustability: Some anti-roll bars offer adjustable settings, allowing drivers to fine-tune the stiffness based on their preferences.
- Material: Look for high-quality materials that ensure durability and performance under stress.
Installation Considerations
Installing new suspension bushings and anti-roll bars can be a rewarding project, but it requires careful consideration:
- Tools Required: Ensure you have the necessary tools, including wrenches, sockets, and potentially a spring compressor.
- Professional Help: If you’re not confident in your mechanical skills, consider seeking professional installation to ensure safety and performance.
- Alignment: After installation, a proper wheel alignment is crucial to maintain handling characteristics.
Conclusion
Upgrading the front and rear suspension bushings and anti-roll bars on a GD WRX can dramatically enhance its handling characteristics. By investing in quality components and considering the factors outlined above, drivers can enjoy a more responsive and stable driving experience. Whether on the track or the street, these improvements can make a significant difference in performance.
