The Subaru WRX STI is renowned for its performance and handling capabilities. However, enthusiasts often seek ways to enhance cornering performance further. Upgrading components with Whiteline and Perrin parts can significantly improve the vehicle’s handling characteristics. This guide will walk you through the essential upgrades to consider for better cornering.
Understanding the Importance of Upgrades
Upgrading your Subaru WRX STI’s handling components can lead to improved stability, responsiveness, and overall driving enjoyment. The right modifications can help you achieve better cornering performance, making your driving experience more thrilling and controlled.
Key Components to Upgrade
- Anti-roll bars
- Control arms
- Sway bar bushings
- Strut tower braces
- Lowering springs
Anti-roll Bars
Anti-roll bars, also known as sway bars, are essential for reducing body roll during cornering. Whiteline offers adjustable anti-roll bars that allow drivers to fine-tune their vehicle’s handling characteristics. By increasing stiffness, you can enhance cornering performance significantly.
Control Arms
Perrin control arms are designed to improve suspension geometry and handling. Upgrading to these components can provide better alignment and increased stability during aggressive cornering. The added strength and adjustability can help optimize your vehicle’s performance on the track or street.
Sway Bar Bushings
Replacing factory sway bar bushings with Whiteline’s polyurethane bushings can improve responsiveness and reduce flex. This upgrade allows for better transfer of forces during cornering, enhancing your vehicle’s overall stability.
Strut Tower Braces
Strut tower braces help to reduce chassis flex, which can negatively impact handling. Installing a Perrin strut tower brace can provide additional support to the suspension, resulting in improved cornering precision and feedback.
Lowering Springs
Lowering springs can lower the vehicle’s center of gravity, which helps reduce body roll and improve cornering dynamics. Whiteline lowering springs are designed to work in harmony with your existing suspension while providing a sportier look and feel.
Installation Tips
When upgrading your Subaru WRX STI, proper installation is crucial. Here are some tips to ensure a successful upgrade:
- Always refer to the manufacturer’s instructions for specific installation guidelines.
- Use the correct tools and safety equipment during installation.
- Consider seeking professional installation if you are not comfortable with mechanical work.
- Perform a thorough inspection of all components before and after installation.
- Test drive the vehicle after installation to ensure everything is functioning as expected.
Testing and Tuning
After installing new components, it’s essential to test and tune your vehicle. This process will help you understand how the upgrades have affected your handling and allow you to make further adjustments if necessary.
Track Testing
Consider taking your WRX STI to a track for testing. This environment allows you to push your vehicle to its limits and evaluate the effectiveness of your upgrades. Pay attention to how the car responds during cornering and make note of any areas that may require further tuning.
Adjustments
Based on your testing, you may need to make adjustments to your suspension settings. This could involve altering the stiffness of your anti-roll bars or adjusting the alignment of your control arms. Fine-tuning these settings can help you achieve the desired handling characteristics.
Conclusion
Upgrading your Subaru WRX STI with Whiteline and Perrin components can lead to significant improvements in cornering performance. By focusing on key components such as anti-roll bars, control arms, and bushings, you can enhance your vehicle’s handling capabilities. Remember to follow proper installation procedures and test your upgrades to ensure maximum performance on the road or track.
