The Bilstein B16 (PSS10) suspension kit for 1999-2005 Porsche 911 pairs monotube dampers with matched springs and a threaded body for ride height adjustment. Its 10-stage manual damping lets you tune rebound and compression for street or track, while zinc coating and a threaded design provide corrosion protection and roughly 30-50mm lowering capability in an OE-quality direct-fit package.
