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.
When the emphasis of a car’s performance is on the best possible road-holding, a lack in ride comfort is an automatic consequence when using conventional shock absorbers. Not so with the KONI FSD technology!
The groundbreaking FSD technology 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 car’s handling. It will give Ride and Handling Engineers a constructive, additional variable in fine-tuning the car’s behaviour.
