Product Details
Koni Special Active shocks for the 1997-2003 BMW 5 Series (E39) use Koni's patented Frequency Selective Damping (FSD) technology to deliver two damping curves in one fixed shock — soft for low-frequency road inputs (comfort) and firm for high-frequency body motion (control). The result is a daily driver that feels composed without compromising ride quality.
FSD reacts to the road, not to a driver setting, so there's nothing to adjust and nothing to wear out. Special Active works with stock springs or factory-spec lowering springs up to ~35 mm of drop, and is built on Koni's long-life twin-tube platform with the lifetime warranty on workmanship.
