FSD is the abbreviation of Frequency Selective Damping. It is the latest technology of Koni, specifically designed to combine the ultimate in comfort and road-holding. This no-compromise shock absorber was launched to the world in 2005. A revolutionary new technique which combines the benefits of firm and comfortable suspension in a single perfect shock absorber. Firm for sporty driving on even road surfaces. Comfortable for a smooth ride on uneven road surfaces.

If you are able to change the damping force level in relation to the frequency of the movement of the vehicle, you create the possibility to solve the conflict in terms of comfort and handling ever present in conventional dampers.

The Koni FSD technology does just that! In effect giving you Active Ride Control. The groundbreaking FSDTechnology has been designed and patented by Koni to end the compromise between comfort and road-holding. This new feature can be used as an integrated part of the hydraulic valving system inside the damper.

Consequently, no additional cables, sensors, or any other electronic devices are needed to operate this system. It operates fully hydraulic and frequency selective and is therefore an economical and effective solution to improving a cars handling. It will give Ride and Handling Engineers a constructive, additional variable in fine-tuning the cars behavior.

The Koni FSD Spring/Shock Kits includes a matched set of Eibach Pro Kit Springs to complement the FSD technology and give your vehicle a lower and more aggressive ride.
