The Bilstein B14 (PSS) is a ride-height-adjustable coilover kit for the Audi S4 and RS4 (B7), built as a direct-fit, OE-quality package. It pairs monotube gas-pressure dampers with matched, application-tuned springs on a threaded, zinc-coated body that allows roughly 30-50mm of lowering and resists corrosion with Triple-C-Technology surface coating. Made in Germany and developed under motorsport conditions at the Nurburgring. Some applications may require OE strut mount 8E0412377C.
