Tein Street Advance Z Coilover Kit – 2006–2011 Honda Civic 8th Generation (FA / FG) | EDFC Compatible | Height & Damping Adjustable | Street & Track

The Tein Street Advance Z Coilover Kit for the 2006–2011 Honda Civic 8th generation is a complete height-adjustable coilover kit with damping force adjustment and EDFC (Electronic Damping Force Controller) compatibility — Tein's mid-tier coilover offering that bridges the gap between the entry-level Flex Z and Tein's full competition coilover lineup. Compatible with the FA sedan and FG coupe body styles. The Street Advance Z's EDFC compatibility allows the driver to adjust damping force from inside the cabin via Tein's optional EDFC Active or EDFC Active Pro controller — eliminating the need to manually adjust the damping dial at each corner. Tein is one of the most respected Japanese suspension brands in the performance aftermarket — a Japanese manufacturer with decades of motorsport and performance suspension development experience.

Key Features:

• EDFC compatible — the Street Advance Z is compatible with Tein's EDFC (Electronic Damping Force Controller) system — allowing damping force adjustment from inside the cabin via the optional EDFC Active or EDFC Active Pro controller without manually adjusting each corner
• Height adjustable — ride height adjustment via the lower spring perch — set the correct ride height for your specific 8th gen Civic build and driving use
• Damping force adjustable — manual damping force adjustment at each corner — tune the damping force to suit different driving conditions, road surfaces, and track configurations
• Covers FA and FG — correct for both the FA sedan and FG coupe body styles of the 8th generation Civic
• Application-specific — engineered specifically for the 2006–2011 Honda Civic 8th generation — correct spring rates, damper valving, and geometry for the 8th gen's suspension layout and weight distribution
• Street and track capable — the Street Advance Z's damping adjustment range covers both comfortable street settings and firmer track settings — a versatile coilover for dual-purpose street and track use
• Tein quality — manufactured by Tein, one of the most respected Japanese suspension brands in the performance aftermarket

EDFC — Electronic Damping Force Controller:

The Street Advance Z's EDFC compatibility is its key differentiator from the entry-level Flex Z. Tein's EDFC (Electronic Damping Force Controller) system uses small stepper motors mounted on each coilover's damping adjustment dial — connected to a cabin-mounted controller that allows the driver to adjust damping force at all four corners simultaneously from inside the car. The EDFC Active and EDFC Active Pro systems can also automatically adjust damping force based on vehicle speed, G-force, and other parameters — providing a semi-active suspension experience at a fraction of the cost of a factory adaptive suspension system. The EDFC system is sold separately — the Street Advance Z coilover kit includes the EDFC motor mounts and is pre-configured for EDFC installation.

Street Advance Z vs. Flex Z — Which Is Right?

• Flex Z: Entry-level damping-adjustable coilover — manual damping adjustment at each corner. The correct choice for owners who want damping adjustability at a lower price point and do not require EDFC compatibility.
• Street Advance Z (this product): Mid-tier coilover with EDFC compatibility — manual damping adjustment plus the option to add Tein's EDFC system for in-cabin damping control. The correct choice for owners who want the convenience of EDFC or plan to add it in the future.

• Set ride height with the vehicle at kerb weight for accurate measurement — lock the spring perch securely after setting the desired ride height
• If adding EDFC: route the EDFC motor cables correctly to avoid contact with moving suspension components — follow Tein's EDFC installation instructions
• Inspect all suspension components (control arm bushings, ball joints, tie rod ends) before installation — worn components should be replaced alongside the coilovers
