Tein Flex Z Coilovers for Infiniti G37, Q40 & Nissan 370Z
Part#: VSP92-C1AS3

FLEX Z inherits all the features and quality of STREET FLEX but the adoption of new platform allows its price to be set at amazingly low price point. FLEX Z, of course, maintains the long-favored "Made in Yokohama" quality. Ride height adjustable shock absorber, fully loaded with TEIN's comprehensive technology, is now more affordable than ever.

Top end of shell pipe is drawn, oil & gas are injected then the opening is completely sealed by crimping process. This "Sealed Structure" process also reduces the production time, compared to the production of existing dampers.

In addition, pursuit of efficient production system, such as use of seam welding, allows us to drastically reduce the production cost.

*Twin-Tube System for Comfortable Ride on Streets!*
Considering the use of larger tires/wheels and the lowered ride height, FLEX Z uses twin-tube system, in the pursuit to ride comfortable on the street.

In order to maintain the ride quality on streets with rough spots here and there, a shock absorber has to have sufficient stroke, be low-frictional and move smoothly.

As an oil chamber and a gas chamber are not arranged serially in a twin-tube system, it is easy to secure enough stroke. Also, low gas pressure keeps friction low.

Its smooth stroke movement makes it possible to follow rough and bumpy road surfaces quite well, offering supple ride at low speed and stable ride at high speed.

*Full-Length System for Ride Height Adjustment w/ Minimal Change in Ride!*
Full-length ride height adjustment system, used for FLEX Z, enables adjustment of ride height by adjusting the case length, without changing the damper stroke length and/or spring pre-load. This has the advantage that the change in ride quality is kept minimal when the height is adjusted.

*Damping Force Adjustable to Change Ride to Desired Settings!*
FLEX Z has ever-popular 16-level damping force adjustment (comp./rebound together) feature with the use of needle valve. By turning the adjustment knob, damping force (stiffness) is adjusted linearly step by step, to change the ride and handling of the car to suit driver's needs/preferences.

Use of well-reputed "ADVANCE Needle" at the needle valve for oil flow control secures sufficient damping force adjustable range. Whether it's for the handling characteristics of sport driving or for the ride quality according to numbers of passengers, finding the most desirable setting is easier than ever. 

*Compatible with EDFC Series to enable In-Car Damping Force Adjustment!*
With EDFC (Electronic Damping Force Controller) series installed, damping force can be controlled from the cockpit with ease. Stepping motors attached in place of adjustment knobs control the damping force quickly and accurately. Use of EDFC turns 16-level adjustment into finer 32-level or 64-level adjustment mode (64-level only available with EDFC ACTIVE / EDFC ACTIVE PRO), to provide the optimum performance by fully utilizing the damping force adjustable range drastically widened by the use of "ADVANCE Needle".
