The ST X coilover kit is an application-specific suspension for the 2008-2013 BMW 128i (E82), engineered by KW in Germany for everyday drivers who want sportier handling without sacrificing road comfort. It offers adjustable ride height across a wide range, with fixed (non-adjustable) damping tuned to the vehicle. Galvanized zinc-coated steel struts and a friction-optimized polyamide composite spring perch with a stainless-steel insert resist corrosion for long-lasting height adjustability, while the integrated dust-protection bump stop shields the chrome piston rod and seals.
