Koni FSD Shocks BMW E90 E92 Xi AWD

Product Description

The KONI FSD (Frequency Selective Damping) shock for the BMW E90 E92 Xi AWD combines excellent road holding and handing characteristics with no-compromise comfort levels. 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 for your BMW are a smart suspension system that adjusts automatically and in a fraction of a second to road conditions and driving style. Price includes (2) front and (2) rear.

Will not fit RWD vehicles.

How It Works:
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.
