The new Flex Z damper is the evolution of our popular Street Flex coilover. Developed to provide the ultimate balance of comfort and performance for both street driving and circuit use, along with wide-range damping force adjustment using our new Advance Needle technology and new damper valving specs, giving the driver a much more noticeable feel in damping force change and controllability. The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height. Full-length adjustability offers separate spring preload and ride height adjustment. Updated internal components and external coatings increase durability and product life. Includes Pillowball Upper Mounts (camber adjustable for strut type applications) and is compatible with the EDFC and EDFC Active systems.
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 range ($800 to $1,050). 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!
Advanced Needle Technology
Tein 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.
Full Length Adjustable
Vehicle ride height and spring pre-load can be adjusted independently. Ride height is adjustable in two ways: a. adjustable shock length, and b. adjustable spring seat.
a. The lower mounting bracket can be adjusted, thus changing the overall length of the shock, and therefore altering the vehicle's ride height. This also allows the user to determine suspension travel and droop.
b. The adjustable spring seat allows for independent adjustment of spring pre-load without affecting vehicle ride height.
Aluminum spring seats are utilized to reduce ceasing of spring seat to threaded body, and for improved durability.
Twin Tube Design
Considering the use of larger tires/wheels and the lowered ride height, FLEX Z uses twin-tube system, in pursuit of ride comfort on streets.
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.
