Upgrading your WRX’s suspension can greatly enhance its performance and handling. In this guide, we will walk you through the step-by-step process of installing a Bilstein or KYB suspension kit on your Subaru WRX.
Tools and Materials Needed
- Bilstein or KYB suspension kit
- Jack and jack stands
- Socket set
- Wrench set
- Screwdrivers
- Torque wrench
- Spring compressor (if necessary)
- Safety glasses
- Gloves
Preparation
Before starting the installation, ensure your vehicle is parked on a level surface. Gather all necessary tools and materials. Wearing safety gear is crucial for protection during the installation process.
Step 1: Lifting the Vehicle
Begin by loosening the lug nuts on the wheels. Use a jack to lift the vehicle and secure it with jack stands. Ensure the car is stable before proceeding.
Step 2: Removing the Old Suspension
Start with the front suspension. Remove the wheel and locate the suspension components. Unbolt the strut assembly from the top and bottom. Carefully detach the sway bar links and any other connected components.
For the rear suspension, repeat the process by removing the rear wheels. Unbolt the struts from the top and bottom, and disconnect any additional parts such as the sway bar links.
Step 3: Installing the New Suspension
With the old suspension removed, take your new Bilstein or KYB struts and position them in place. For the front, align the strut assembly and bolt it securely at both the top and bottom. Make sure to follow the manufacturer’s torque specifications.
For the rear, repeat the installation process by securing the new struts in the same manner. Ensure all components are fastened tightly and in the correct order.
Step 4: Reinstalling Other Components
Reconnect any components that were detached during the removal process, such as sway bar links and brake lines. Ensure everything is aligned properly and check for any obstructions.
Step 5: Replacing the Wheels
Once the new suspension is installed and all components are reattached, it’s time to put the wheels back on. Hand-tighten the lug nuts before lowering the vehicle back to the ground.
Step 6: Lowering the Vehicle and Final Checks
Lower the vehicle back to the ground using the jack. Once it’s on the ground, use a torque wrench to tighten the lug nuts to the recommended specifications. This will ensure that the wheels are securely fastened.
Step 7: Alignment and Testing
After installation, it’s crucial to have the alignment checked. A proper alignment will prevent uneven tire wear and ensure optimal performance. Take your WRX for a test drive to feel the improvements in handling and ride quality.
Conclusion
Installing a Bilstein or KYB suspension kit on your WRX can significantly enhance its performance. By following this step-by-step guide, you can ensure a successful installation and enjoy a more responsive driving experience.
