ST Adjustable lowering springs for 2005–2011 Audi A6 sedan (C6/4F) convert standard suspension into a height-adjustable system via a threaded sleeve, compatible with vehicles that have electronic or standard dampers. Made from chrome-silicon steel and multi-tempered, these springs provide application-specific rates for a lower center of gravity, improved handling, and adjustable ride height without a full coilover conversion.
