The Air Lift Performance rear kit for 2015–2021 Subaru WRX/STi replaces the rear suspension with air springs and threaded‑body monotube shocks to drop ride height up to 5.1 inches from stock. The system pairs double‑bellow air springs with monotube dampers, offers 30 clicks of damping adjustment, independent ride‑height tuning, reduced unsprung mass versus coils, and is supplied with components tested for long life and a one‑year warranty.
