ST Adjustable Lowering Springs for select Audi models (2012–2018 A6/A7 C7/4G and 2009–2016 A4/S4 B8, 2WD/4WD) convert stock suspension into a height‑adjustable system without replacing dampers. The chrome‑silicon steel springs use vehicle‑specific rates and a threaded sleeve for perfect fitment, allowing height adjustment like a coilover while retaining electronic damper function where equipped.
