ST Suspensions X Coilovers - BMW F30/F32 (xDrive) 2013-2020

The ST X coilover kit is a height-adjustable suspension developed by ST suspensions for everyday drivers who want sharper handling without sacrificing ride comfort. Damping is fixed and tuned in Germany for this specific BMW xDrive (AWD) application, with springs and dampers built by hand and shock-dyno tested at KW in Fichtenberg. Ride height is set through a friction-optimized polyamide composite spring perch with a stainless-steel insert, while galvanized zinc-coated steel strut housings and an integrated dust-protection system guard against corrosion and contamination for long service life.
