OVERVIEW
The ST X coilover kit for the E82 1 Series coupe replaces the factory struts and springs with a height-adjustable coilover set for a lower stance and firmer body control.
ST is the value brand of KW Automotive, and every ST coilover is built by hand at KW in Fichtenberg, Germany. The ST X is the entry point in the coilover range: a fixed-damping, height-adjustable kit built on galvanized zinc-coated steel struts with a friction-optimized composite spring perch and stainless steel insert.
