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.
How It Works (Refer to second image above):
In standard shock absorbers the main damping characteristic is defined by the oil flow going through the piston assembly (1). Combining it with the FSD feature (2), KONI added a special valve that controls an oil flow parallel to the one going through the piston rod (3). This parallel oil flow is closed by the FSD feature, giving a rise in damping force almost linear to the time that the piston is moving in one direction.
Put simply: the 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. Since it is an integrated part of the hydraulic valve system inside the damper, no additional cables, sensors or any other electronic devices are needed to operate an FSD damper.

A definite change in the feel of the car. You can feel the more progressive behavior as the suspension loads up. Combined with non-run flats, the entire feel of the car is dramatically transformed.

I had the shocks installed along with texas speed works springs. I was concerned that with my 18" run flat tires the ride would be rough. On the contrary the shocks do an excellent job of controlling spring movement. The ride is exceptional. Small and large impacts are easily absorbed and the ride is very very smooth. All of the small vibrations that were transmitted by the stock shocks are completely smoothed out. The acid test was my 70 year old mother. After taking her for a ride she swears that my mini rides better than her Mercedes ML suv. I don't know about that, but I am impressed. I expected the FSD's to be good . But not this good.
