Tein S.Tech lowering springs for 2004–2007 Subaru WRX sedan and wagon, and 2004 STi, are a vehicle-specific spring set that lowers ride height to refine stance and handling for supported WRX/STi applications. These springs are intended to provide a firmer, more responsive feel than factory springs while maintaining everyday usability across the listed Subaru models and body styles.
