OVERVIEW
The ST XTA coilover kit for the rear-drive E91 Sports Wagon and E93 Convertible 3 Series pairs rebound-adjustable KW dampers with aluminum uniball top mounts.
ST is the value brand of KW Automotive, and every ST coilover is built at KW in Germany on galvanized steel strut housings sealed against corrosion, with a continuous thread so ride height can be set with the kit installed.
