5. Installation

Installation of coilovers requires mechanical knowledge and specialized tools. If you are not confident in your abilities, seek professional assistance.

5.1 General Installation Steps

1. Safely lift and support the vehicle. Remove the wheels.
2. Remove the original suspension components.
3. Assemble the new coilover units if necessary (refer to video below).
4. Install the new coilovers, ensuring all bolts are torqued to manufacturer specifications.
5. Reinstall the wheels and lower the vehicle.
6. Perform a wheel alignment immediately after installation.

5.2 Coilover Assembly (if required)

5.3 Height Adjustment

The coilovers allow for independent ride height adjustment. Use the provided C spanners to adjust the lower mount.

1. Loosen the lower mount (A) and locking ring (B).
2. Increase or decrease the thread distance to change the ride height.
3. Tighten the lower mount (A) and locking ring (B) securely.

6. Operating Instructions (Damping Adjustment)

Your coilovers feature 24 levels of rebound damping adjustment to suit various driving conditions and preferences. The adjustment knob is located at the top of the coilover.

• Levels 0-8: Recommended for street use, providing a comfortable ride.
• Levels 9-16: Suggested for mountain roads or spirited driving, offering a balance of comfort and performance.
• Levels 17-24: Ideal for race tracks, providing maximum stiffness and control.

Turn the adjustment knob clockwise for firmer damping and counter-clockwise for softer damping. Make adjustments incrementally and test the vehicle's handling to find your preferred setting.

7. Maintenance

• Regularly inspect coilovers for any signs of damage, leaks, or corrosion.
• Keep the coilover threads clean and free of debris. Applying a thin layer of anti-seize grease can help prevent seizing.
• Check all mounting bolts and nuts periodically to ensure they are properly torqued.
• Clean the coilovers with mild soap and water, especially after driving in harsh conditions (e.g., salt, dirt).

9. Troubleshooting

• Unusual Noises (Clunking/Squeaking): Check all mounting points for proper torque. Inspect for any loose components or contact between parts.
• Uneven Ride Height: Re-measure and adjust the coilover height on each corner. Ensure spring preload is correctly set.
• Poor Handling/Ride Quality: Verify damping settings are appropriate for your driving conditions. Check for proper wheel alignment.
