KONI Special Active FSD Shock for 1999-2005 Porsche 911 (996) qa1-short-transmission-crossmember-with-powerglide Part Number 4055665SW Part NameKONI Special Active shocks for the 1999 2005 Porsche 911 (996) 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
