Performance Tein Flex Z Coilover System for 2015 - 2021 Subaru WRX/STI by TEIN

FLEx Z inherits all the features and quality of STREET FLEx but the adoption of a new platform allows its price to be set at amazingly low range. 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 prices than ever.

Until now, all TEIN dampers can be disassembled for overhaul; Now, we introduce our new "Sealed Structure" for the FLEx Z. Below is a brief description of this new production process for our FLEx Z at TEIN HQ Factory in Yokohama, Japan. The top end of the 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 disassembable dampers. In addition, the pursuit of an efficient production system, such as the use of seam welding, allows us to drastically reduce the production cost.
