5. Operating Instructions
5.1. Damping Adjustment
The Bilstein B16 (PSS10) system features 10-stage damping adjustment. This allows for fine-tuning of both rebound and compression characteristics simultaneously. The adjustment knob is typically located at the bottom of the shock absorber body (for front coilovers) or at the top (for rear shocks, depending on application). Turning the knob will cycle through the 10 settings, from softest to firmest.
- Setting 1: Softest damping, suitable for comfortable street driving.
- Setting 10: Firmest damping, ideal for aggressive track use or highly dynamic driving.
- Adjust both front and rear dampers to the same setting or a balanced combination for optimal performance.
- Always adjust dampers when the vehicle is stationary and safe to access the adjustment knobs.
5.2. Ride Height Adjustment
The threaded body design of the Bilstein B16 (PSS10) allows for precise ride height adjustment. This adjustment is made by rotating the spring perch collars on the threaded body of the shock absorber. Use the provided spanner wrenches for this procedure.
- To Lower: Rotate the spring perch collars downwards on the threaded body.
- To Raise: Rotate the spring perch collars upwards on the threaded body.
- Ensure both sides of the vehicle (front or rear axle) are adjusted equally to maintain balance.
- After any ride height adjustment, it is crucial to have a professional wheel alignment performed.
- Do not exceed the maximum or minimum ride height settings specified by Bilstein to prevent damage or unsafe driving conditions.
6. Maintenance
Regular maintenance helps ensure the longevity and performance of your Bilstein B16 (PSS10) suspension system.
- Regular Inspection: Periodically inspect all suspension components for signs of wear, damage, or corrosion. Check for loose bolts, cracked bushings, or leaking dampers.
- Cleaning: Keep the threaded bodies and adjustment collars clean from dirt, salt, and debris. Use mild soap and water, then rinse thoroughly. Avoid harsh chemicals that could damage finishes or seals.
- Torque Checks: After initial installation and periodically thereafter, verify that all mounting bolts are torqued to the vehicle manufacturer's specifications.
7. Troubleshooting
If you experience issues with your suspension system, consider the following:
- Unusual Noises: Check for loose mounting hardware, worn bushings, or components rubbing against each other.
- Uneven Ride Height: Verify that the ride height adjustments are identical on both sides of an axle. Ensure no components are binding. A post-installation alignment is critical.
- Poor Handling: Re-check damping settings. Ensure they are appropriate for your driving conditions. Verify tire pressure and wheel alignment.
- Leaking Dampers: A small amount of oil residue is normal, but significant leakage indicates a seal failure. Contact Bilstein support or a qualified technician.
For persistent issues, consult a professional automotive technician or contact Bilstein customer support.
