TEIN MONO SPORT Coilover Kit Lexus IS350 F-Sport GSE31L FR 2014-2017 USA- GSQ74-71AS3

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.
  • The 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.
• 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.
  Newly-Designed Upright Strong Tube for Strut Type Suspensions
  • For strut type suspensions, which require high lateral stiffness, the world's first 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.
• 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
  • 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.)
• Smooth Ride Height Adjustment & One-of-A-Kind Adjusting Wrench
  • MONO SPORT has adopted the new wrought aluminum spring seats and low-friction hard-resin thrust washers. These effectively reduces the friction with springs, caused during ride height adjustment, and makes it easier to adjust the ride height with pre-load on the springs.
  • Shell cases are treated with "ZT Coating", a superlow-friction fluorine resin coating, which is tightly baked onto the surface in-house. This special coating provides superior protection against rust and high lubricity, for keeping a smooth adjustment for a long period.
  • MONO SPORT kit includes one-of-a-kind user-friendly ride height adjusting wrench. It has a 12.7mm (1/2in) sq. hole for attaching spinner handle and/or torque wrench for tightening at high torque.
• No-Sag Spring
  • Included springs are made of high-tensile steel SAE9254 (tensile strength 200kgf/mm2 or over) and cold formed for excellent resistance to sagging and for superior quality stability.
  • Surface is powder coated for superb protection against chipping & peeling, for high durability and for superior anti-corrosion performance. High-quality spring can be used under various conditions without any worry.
  • The most suitable shape of spring (straight or barrel-shaped) is determined for each vehicle model, to provide wide ride height adjustable range and to secure sufficient stroke without compromising ride comfort.
• High-Spec Damper Oil
  • Specially-formulated high-spec oil exhibits stable viscosity characteristics at any temperature from low to high, to allow shock absorbers to stroke smoothly and to generate damping force stably under various conditions.
  • The oil has superior anti-foaming characteristics hence the bubble cavitation and/or thermal degradation hardly occurs, making it even suitable for tough sport driving.
  • The oil also does not deteriorate much with age, making it possible to maintain and deliver superior performance for the long term.
