Tein Mono Sport Coilovers for Infiniti G37, Q40 & Nissan 370Z
Part#:  GSP92-71AS3

The main concept of MONO SPORT is to provide driving pleasures to all drivers. All the different needs and demands are carefully analyzed to come up with the most suitable settings for each and every vehicle models.

For cars often running on circuit, the settings are focused more on sport driving. MONO SPORT offers not only the precise steering feel that strongly appeals to sport-minded drivers, but also the flexible movement. MONO SPORT is set up to let the drivers enjoy the runs on circuits and/or winding roads and everyday driving on streets with the damping force adjusted.

For cars requiring comfortable ride more than anything, touring settings are applied to provide and maintain the finest ride comfort which are often lost when the vehicle is lowered and/or larger tires/wheels are used. MONO SPORT offers the finest and most comfortable ride feel that makes even a long-distance driving seem like a breeze.

Mono-Tube Structure to Deliver Rich Information from Road Surface!
Mono tube structure of MONO SPORT completely separates the oil chamber and the gas chamber and hence aeration does not occur. This enables stable generation of linear damping force, reacting to the finest changes in road surfaces, even when running aggressively and repeatedly on circuits. With this, superior-quality MONO SPORT offers capability for the most delicate control of the vehicle and for the deepest level of communication with the roads.

Exclusively-designed urethane bump rubber absorbs and softens the compression impact effectively, maintaining ride comfort when going over gaps etc and preventing the damper from bottoming out.
(Image shown is for wishbone/multi-link type suspensions. Some vehicle models use OE bump rubbers.)

Full-Length System for Ride Height Adjustment w/ Minimal Change in Ride!
Full-length ride height adjustment system, used for MONO SPORT, 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.
This system not only makes it possible to maintain good balance between the low-down appearance and ride comfort, but also provides more setting choices for sport driving as well.

Newly-Designed Upright Strong Tube for Strut Type Suspensions!
For strut type suspensions, which require high lateral stiffness, the world's first (*1) triple- tube-structured "Upright Strong Tube" is newly adopted. It reduces friction with the use of revised internal lubrication method. Damping force adjustment knob attached to the top of the shock absorber allows easier access and makes the installation of EDFC motors (optional) a breeze. Waterproofing process, which is a must for inverted types, is reduced/simplified greatly. The most advanced technology, cultivated in various rally events all over the world such as WRC and ERC, is now available to everyone.

16-level Damping Force Adjustment (Comp./Rebound Together) + ADVANCE M.S.V.!
MONO SPORT comes with the well-established 16-level damping force adjustment feature (compression & rebound together) and equipped with exclusively-designed "ADVANCE M.S.V.". "ADVANCE M.S.V." is a sub-valve system composed of a combination of 2 mechanisms; "ADVANCE Needle" to increase the damping force adjustable range and "M.S.V. (Micro Speed Valve)" to elimitate unwanted decline of damping force in micro speed range. Both these components are redesigned exclusively for MONO SPORT.
With the use of "ADVANCE M.S.V.", damping force adjustable range is made about three times wider, yet superior damping force characteristics are maintained in all parts to improve steering response, road ability and traction performance.

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 M.S.V. ".

With EDFC ACTIVE / EDFC ACTIVE PRO, damping force can be controlled automatically according to changes in G-force and/or vehicle speed, to offer very smooth and slick ride like never before. (Some models are NOT compatible with EDFC series.)
