6. Setup and Installation
Professional installation and alignment are strongly suggested for this product. An instruction manual is included with the product. Please adhere to the following guidelines:
- All modifications must be installed by licensed mechanics and comply with local modification regulations.
- Ensure all components are tightened with the correct torque specifications. Refer to your vehicle's service manual for precise torque values. Loose nuts, bolts, or locks can cause noise and potential safety issues.
- Do not use an impact wrench during installation, as it can loosen or damage the product.
- Examine the clearance between tires and suspension components. A minimum clearance of 4mm is required. If clearance is insufficient, wheel spacers may be necessary. (Caution: This may not be sufficient with torsion beam trailing arm axles).
7. Operating Instructions
The COT6 Series coilovers offer 24 levels of damping adjustment, allowing you to customize your ride feel. Adjustments are typically made via a knob or dial on the top or bottom of the shock absorber.
- Damping Adjustment:
- For a comfortable daily drive, set the damping to full soft.
- For more spirited driving, a setting around 16 clicks (from full soft) is often recommended.
- For occasional track days or maximum performance, set the damping to full stiff.
- Height Adjustment: The coilovers allow for a lowering adjustment of 25-75mm. This adjustment is separate from spring preload, ensuring ride quality is maintained across different ride heights.
8. Maintenance
To ensure the longevity and optimal performance of your coilovers, regular maintenance is recommended:
- Spray the coilover components with a lubricant like WD40 every 3-4 months. This helps keep them smooth, clean, and extends their lifetime.
- Periodically inspect all nuts, bolts, and connections for tightness.
- Check for any signs of wear, damage, or leaks on the shock absorbers and springs.
9. Troubleshooting
If you experience any issues with your coilover system, consider the following:
- Noise from Suspension: Any loose nuts, bolts, or locks can cause rattling or knocking noises. Immediately check and tighten all components to their correct torque specifications to prevent further problems.
- Poor Ride Quality: Review your damping settings. If the ride is too harsh, try softening the damping. If it feels too bouncy or uncontrolled, try increasing the damping stiffness.
- Uneven Ride Height: Ensure that both sides of the vehicle are adjusted to the same height. Re-check height adjustments and spring preload settings.
10. User Tips
- Experiment with Damping: Take the time to experiment with the 24-way adjustable damping settings. Start with softer settings for daily comfort and gradually increase stiffness for improved handling and responsiveness on different road conditions or for performance driving.
- Regular Inspections: After initial installation and after any significant adjustments, perform a visual inspection and a short test drive to ensure everything is functioning correctly and securely.
