The Tein Street Basis Z coilover is a street-oriented suspension solution for 2008 and later Subaru WRX STI five-door models and 2011 and later STI four-door applications. It replaces standard springs and dampers to refine everyday ride quality and handling for street use. Geared toward owners updating their STI's suspension, the Street Basis Z offers a consolidated approach without altering primary chassis attachments.
