The Tein S.Tech spring set for 2015 and later Subaru WRX and WRX STI models replaces factory springs with a performance-oriented spring package tuned to lower ride height and sharpen handling response. These springs are intended as a direct-fit suspension upgrade to improve cornering behavior and support aftermarket alignment and wheel setups while remaining appropriate for street-driven WRX and STI applications.
