Tein Street Advance Z Coilover Suspension Kit User Manual

1. Product Overview

The Tein Street Advance Z Coilover Suspension Kit (Model GSB14-9UAS2) is designed for the 2006-2011 Honda Civic (FA1, FG1) and Honda Civic SI (FA5, FG2). This suspension system features a thread-type adjustable design, twin-tube construction, and is compatible with original equipment (OE) mounts. It offers damping force adjustability and is compatible with the Electronic Damping Force Controller (EDFC) system.

Key components include cold-formed SAE9254 steel springs, known for their sag-proof and resilient properties, protected by a durable powder coating for rust prevention. The system incorporates a fully sealed damper structure, enhancing durability and simplifying maintenance.

2. Installation and Setup

Installation of the Tein Street Advance Z Coilover Suspension Kit requires specialized tools and expertise. It is highly recommended that installation be performed by a qualified professional technician to ensure proper fitment, safety, and performance. Incorrect installation can lead to vehicle damage or unsafe driving conditions.

2.1. Ride Height Adjustment

The ride height can be adjusted by manipulating the lower spring seat. This thread-type adjustment allows for precise control over the vehicle's stance.

2.2. Pre-Installation Checks

• Verify all components are present and undamaged.
• Ensure compatibility with your specific vehicle model (2006-2011 Honda Civic/SI).
• Refer to the vehicle's service manual for specific torque specifications and removal/installation procedures of original suspension components.

3. Operation and Adjustment

The Street Advance Z coilovers feature damping force adjustability, allowing you to fine-tune the ride characteristics to suit various driving conditions and personal preferences.

3.1. Damping Force Adjustment

Damping force is adjusted via a dial located at the top of the damper shaft. Turning the dial changes the damping characteristics, ranging from soft to hard settings.

Consider the following guidelines for adjusting damping force:

• City Streets: Softer settings (closer to 0) typically provide a more comfortable ride over uneven surfaces.
• Highways: A balanced setting can offer a firm yet stable ride for sustained speeds.
• Winding Roads: Harder settings (closer to 16) can enhance handling and responsiveness for spirited driving.

3.2. EDFC Compatibility

This coilover kit is compatible with the Tein Electronic Damping Force Controller (EDFC) system (sold separately). EDFC allows for remote adjustment of damping force from within the vehicle's cockpit, providing convenience and quick adaptation to changing driving environments.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Tein Street Advance Z Coilover Suspension Kit.

• Regular Inspection: Periodically inspect the coilovers for any signs of damage, leaks, or loose components. Check the dust boots for tears or wear, as they protect the piston rod from foreign material.
• Cleaning: Keep the coilover units clean, especially the threaded sections and adjustment dials, to prevent dirt and debris from hindering adjustments or causing wear. Use mild soap and water, avoiding harsh chemicals.
• Rust Prevention: The springs feature a durable powder coating for rust protection. Avoid scratching or damaging this coating. If damage occurs, address it promptly to prevent corrosion.
• Torque Checks: After initial installation and periodically thereafter, verify that all mounting bolts are torqued to the manufacturer's specifications.

5. Troubleshooting

If you experience issues with your coilover suspension, consider the following common troubleshooting steps:

• Unusual Noises (Clunking/Squeaking):
  • Check for loose mounting bolts or components.
  • Inspect for contact between suspension components and other vehicle parts.
  • Verify that springs are seated correctly and not binding.
• Poor Ride Quality (Too Harsh/Too Soft):
  • Re-evaluate damping force settings. Adjust according to driving conditions and preference.
  • Ensure ride height is set appropriately and not causing bottoming out or topping out.
• Uneven Ride Height:
  • Measure ride height at all four corners and adjust the lower spring seats as necessary to achieve desired balance.
  • Ensure vehicle is on a level surface during measurement.
• Leaking Damper:
  • A leaking damper indicates internal seal failure. This typically requires replacement of the damper unit. Contact Tein support or an authorized dealer.

For persistent issues, consult a professional suspension specialist or contact Tein customer support.
