KONI Special Active FSD Shock (Rear) for 2011-2017 BMW 5 Series (F11) Forte GT 2005 Chevrolet AstroKONI Special Active shocks for the 2011 2017 BMW 5 Series (F11) 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
