Product Description

Since 1985 Tein has been producing aftermarket dampers for the automotive industry. While initially the designs were cerated as OEM replacements, Tein soon began expanding it's knowledge into the automotive race and competition segment. The name Tein is a combination of TEchnical INnovation, which is something the company always strives to achieve.

Tein Flex Z coilovers were created in response to the aftermarket industry's demand. After a rough patch following a slew of replica products, Tein is stronger than ever and releasing their new line of aftermarket coilovers. The Flex Z use a twin tube structure with fully threaded pistons for easy replacement and repair. The Flex Z are also compatible with Tein's revolutionary EDFC system and are still 100% made in Japan.

The Flex Z coilovers for the 2015+ Subaru WRX & WRX STI are compatible with AT and MT models. They include linear 70mm springs which allow for an easy spring swap. Reinforced rubber upper mounts are included in this model and like all Flex Z are 16 way dampening adjustable. If you are searching for an affordable entry level coilover system for your WRX or STi the Flex Z are a perfect option!
