The Tein Street Basis Z incorporates many of the same technologies that have made the Street Basis so popular by enthusiasts, but now made even more affordable by a streamlined manufacturing process and a fully sealed damper structure. Never before has TEIN been able to provide such high quality and performance into an incredibly affordable package, until now!

Developed to provide a sporty ride feeling and aggressive stance. The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height. Vehicle ride height is adjustable via the ZT coated threaded sleeve. Updated internal components and external coatings increase durability and product life. Street Basis Z dampers are great for daily driving and spirited driving for all types of drivers. Made in Japan under strict quality control standards and developed by highly trained suspension engineers.
