Will TEIN Street Basis Z coilover kit GSS60-8USS2 (GD/GG Impreza) fit a Subaru WRX (GD/GG, 2002-2007)?

Q: Will TEIN Street Basis Z coilover kit GSS60-8USS2 (GD/GG Impreza) fit a Subaru WRX (GD/GG, 2002-2007)?

Yes, reportedly. TEIN USA's own application list names kit GSS60-8USS2 for the 2002-2007 WRX sedan and wagon and the 2004 STI. The 2005-07 STI is not on the list, so do not assume it fits those cars. The source is a 2016 manufacturer post, not a spec sheet, so this stays at tier 2; check TEIN's current application chart before buying. Suspension is safety-critical: have it fitted and aligned by someone qualified.
