Product details
OVERVIEW
ST adjustable lowering springs for the GR Supra and G29 Z4 with electronic (adaptive) dampers. The factory dampers and their electronic control stay in place.
ST is the value brand of KW Automotive. ST adjustable lowering springs sit between fixed lowering springs and a full coilover: they keep the car's factory dampers but let you set ride height within ST's tested range instead of accepting one fixed drop. Height is set with threaded sleeves supplied in the kit.
