About Tein

Tein has engineered suspension systems in Japan since 1985, developing coilovers, dampers, and electronic damping controllers for street, drift, and motorsport use. The Street Advance Z line, which includes the GST76-91SS2, updates Tein's original Street Advance dampers with revised internals and external coatings for improved durability, while keeping the same 16-way damping control and full-length ride height adjustment that Tein suspension is known for.
