The Subaru WRX STI is renowned for its performance and handling capabilities. However, for enthusiasts looking to elevate their driving experience, upgrading the suspension and chassis components can make a significant difference. In this article, we will explore the benefits of upgrading to KW Variant 3 coilovers and Cusco strut bars, focusing on how these modifications can enhance handling and cornering.
Understanding the Importance of Suspension Upgrades
Upgrading the suspension system is crucial for improving a vehicle’s handling characteristics. The suspension plays a vital role in how a car responds to steering inputs, maintains traction, and absorbs road imperfections. For the Subaru WRX STI, which is already a performance-oriented vehicle, enhancing the suspension can lead to even greater agility and stability.
Benefits of Coilover Suspension
Coilovers offer adjustable ride height and damping settings, allowing drivers to customize their suspension setup according to their driving style and conditions. The KW Variant 3 coilovers are particularly popular among enthusiasts for several reasons:
- Adjustable Damping: The KW Variant 3 features independent compression and rebound adjustments, providing a tailored driving experience.
- Improved Handling: By lowering the center of gravity, coilovers enhance cornering stability and reduce body roll.
- Quality Construction: KW is known for its high-quality materials and engineering, ensuring durability and performance.
Upgrading to KW Variant 3 Coilovers
Installing KW Variant 3 coilovers on your Subaru WRX STI involves several steps. Here’s a brief overview of the installation process:
- Preparation: Gather the necessary tools and ensure you have a clean workspace.
- Remove Stock Suspension: Safely lift the vehicle and remove the wheels. Disconnect the stock struts and springs.
- Install Coilovers: Position the KW coilovers in place and secure them according to the manufacturer’s specifications.
- Adjust Ride Height: Set the desired ride height before fully tightening the components.
- Reinstall Wheels: Put the wheels back on and lower the vehicle to the ground.
- Alignment: After installation, perform a wheel alignment to ensure optimal handling.
Tuning the Damping Settings
Once the KW Variant 3 coilovers are installed, tuning the damping settings is essential for achieving the desired performance. Start with the manufacturer’s recommended settings and make adjustments based on your driving preferences. Consider the following:
- Soft Settings: For a more comfortable ride on the street, keep the settings on the softer side.
- Stiff Settings: For track use, increase the stiffness to improve responsiveness and cornering performance.
The Role of Strut Bars in Handling
Strut bars are another critical component in enhancing the handling of the Subaru WRX STI. They connect the strut towers, reducing chassis flex during aggressive cornering. The Cusco strut bars are well-regarded for their effectiveness and quality.
Benefits of Cusco Strut Bars
Installing Cusco strut bars can provide several advantages:
- Increased Rigidity: Strut bars help maintain the structural integrity of the chassis, leading to improved handling.
- Better Steering Response: Reduced flex allows for more precise steering inputs, enhancing overall control.
- Easy Installation: Cusco strut bars are designed for a straightforward installation process, requiring minimal tools.
Installing Cusco Strut Bars
The installation of Cusco strut bars on a Subaru WRX STI is relatively simple. Here’s a quick guide:
- Gather Tools: Ensure you have the necessary tools, including a socket set and torque wrench.
- Access the Engine Bay: Open the hood and locate the strut towers.
- Position Strut Bars: Align the Cusco strut bars with the strut towers and secure them using the provided hardware.
- Tighten Bolts: Use a torque wrench to tighten the bolts to the manufacturer’s specifications.
Conclusion
Upgrading the suspension and chassis components of your Subaru WRX STI with KW Variant 3 coilovers and Cusco strut bars can significantly enhance handling and cornering performance. These modifications allow for a more responsive and enjoyable driving experience, whether on the street or the track. With proper installation and tuning, you can take your WRX STI to new heights in performance and handling.
