Tein Flex Z Coilover Damper Kit – 2009–2021 Nissan 370Z (Z34) | 16-Way Damping Adjustment | Height Adjustable | Street & Track

The Tein Flex Z Coilover Damper Kit for the 2009–2021 Nissan 370Z (Z34) is a complete height-adjustable coilover kit featuring 16-way damping force adjustment — giving 370Z owners precise control over both ride height and damping characteristics for a wide range of street and track applications. The Flex Z is Tein's entry-level damping-adjustable coilover — a significant step up from height-only adjustable coilovers, providing the ability to tune the damping force to suit different driving conditions, road surfaces, and track configurations. 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, and one of the most trusted coilover brands for JDM and Japanese-platform enthusiasts worldwide.

Key Features:

• 16-way damping force adjustment — 16 individual damping force settings adjustable via the top-mounted adjustment dial — tune the damping force from a softer street setting to a firmer track setting without tools
• Height adjustable — ride height adjustment via the lower spring perch — set the correct ride height for your specific 370Z build and driving use
• Application-specific — engineered specifically for the 2009–2021 Nissan 370Z (Z34) — correct spring rates, damper valving, and geometry for the Z34's suspension layout and weight distribution
• Street and track capable — the Flex Z's 16-way 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 — decades of motorsport and performance suspension development experience

16-Way Damping Adjustment — Why It Matters:

A coilover with damping adjustment gives the driver control over how the suspension responds to road inputs — softer damping settings allow the suspension to move more freely over bumps and road imperfections for improved ride comfort, while firmer settings reduce body motion and improve handling precision for track use. The Tein Flex Z's 16-way adjustment provides a meaningful range of damping settings — from a street-comfortable setting that works well for daily driving on imperfect roads, to a track-appropriate setting that minimizes body roll and improves cornering response. The ability to adjust damping without tools (via the top-mounted dial) means the driver can change settings quickly between street and track use without requiring a suspension specialist.

Tein Flex Z — The Platform:

The Tein Flex Z is Tein's entry-level damping-adjustable coilover — positioned above height-only adjustable coilovers (like the Tein Street Basis Z) and below Tein's fully adjustable competition coilovers (like the Tein Super Racing). The Flex Z is the correct choice for 370Z owners who want damping adjustability for street and occasional track use without the cost and complexity of a full competition coilover. The application-specific spring rates and damper valving are developed by Tein for the Z34 platform — correct for the 370Z's VQ37VHR V6 weight distribution and suspension geometry.

What's Included:

• Tein Flex Z front coilover assemblies (pair)
• Tein Flex Z rear coilover assemblies (pair)
• All required mounting hardware
• Refer to Tein's product documentation for complete kit contents and installation specifications

Installation Notes:

• Professional installation by an experienced suspension specialist recommended — coilover installation on the Z34 370Z requires correct torque specifications, correct spring perch height setting, and a four-wheel alignment after installation
• A four-wheel alignment is required after coilover installation — do not drive the vehicle at speed before a full alignment is performed
• Set ride height with the vehicle at kerb weight for accurate measurement — lock the spring perch securely after setting the desired ride height
• Start with the damping adjustment at the middle of the 16-way range (setting 8) and adjust from there based on driving conditions and personal preference
• Inspect all suspension components (control arm bushings, ball joints, tie rod ends) before installation — worn components should be replaced alongside the coilovers
• Refer to Tein's installation documentation for complete installation specifications and torque values

Why Tein?

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 and one of the most trusted coilover brands for JDM and Japanese-platform enthusiasts worldwide. Tein's application-specific coilover development — correct spring rates, correct damper valving, and correct geometry for each specific platform — ensures that the Flex Z performs correctly on the Z34 370Z rather than being a generic coilover adapted to fit. For 370Z owners who want a quality damping-adjustable coilover from a brand with proven Japanese suspension credentials, Tein Flex Z is the correct choice.
