The koni fsd (frequency selective damping) shock combines excellent road holding and handing characteristics with no-compromise comfort levels. It 's a two-in-one solution from koni that doesn 't require the installation of sophisticated electronics, cables or sensors. Firmness for sporty driving on even road surfaces. Smoothness for a comfortable ride on uneven road surfaces.

It 's possible via koni 's patented frequency selective damping technology - technology that actively controls the damping level on the basis of the vehicle 's body and suspension movement frequency. Fsd shocks are a smart suspension system that adjusts automatically and in a fraction of a second to road conditions and driving style. He fsd feature is a hydraulic amplifier that delays the build up of pressure. In some ways an extra tuning option has been created in order to get the best possible combination of handling and comfort.
