Tools and Materials Needed
Before starting the installation, ensure you have the following tools and materials:

Step-by-Step Installation Process
1. Prepare the Vehicle
Begin by parking the vehicle on a flat surface and engaging the parking brake. Loosen the lug nuts on the wheels but do not remove them yet. Use a jack to lift the vehicle and secure it with jack stands.
2. Remove the Stock Suspension
Once the vehicle is secure, remove the wheels. Start by removing the lower bolt from the shock absorber using a socket wrench. Next, remove the upper mounting bolts from the strut tower. Carefully take out the stock strut assembly.
3. Install the Bilstein Coilovers
Before installing the new coilovers, adjust the ride height according to your preference. Attach the new coilover assembly to the lower control arm and secure it with the lower bolt. Then, position the upper mount in the strut tower and fasten it with the upper bolts.
4. Repeat for All Corners
Repeat the removal and installation process for the remaining corners of the vehicle. Ensure that each coilover is installed securely and that all bolts are tightened to the manufacturer’s specifications.
5. Adjust Damping Settings
Once all coilovers are installed, adjust the damping settings to your desired preference. The PSS9 system allows for fine-tuning based on driving style and road conditions.
6. Reinstall Wheels and Lower the Vehicle
After all adjustments are made, reinstall the wheels and hand-tighten the lug nuts. Lower the vehicle off the jack stands and then fully tighten the lug nuts to the specified torque.
Testing the New Suspension
After installation, it’s crucial to test the new suspension system. Take the vehicle for a test drive to evaluate handling, ride comfort, and overall performance. Make any necessary adjustments to the damping settings based on your experience.
Conclusion
Upgrading the suspension of your E46 M3 with Bilstein PSS9 coilovers can significantly enhance your driving experience. By following the installation steps outlined above, you can achieve superior handling and a more enjoyable ride. Always remember to regularly check the suspension components for wear and make adjustments as needed to maintain optimal performance.
