Koni FSD ("Frequency Selective Damping") dampers are specifically designed to combine the ultimate in comfort and road-holding.
FSD technology uses a revolutionary new technique to combine 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.
This new feature is an integrated part of the hydraulic valving system inside the damper. Consequently, there are no additional cables, sensors, or any other electronic devices needed to operate this system.
How does it work?The split between comfort and handling can be defined in two frequency areas:
For comfort, with the suspension moving in a high frequency area (± 10 Hz), asking for low damping forces.
For handling, with the suspension moving in a low frequency area (± 1 Hz), asking for high damping forces.
By changing the damping force level in relation to the frequency of the movement, it is possible to resolve the conflict in terms of comfort and handling ever present in conventional dampers.
In standard shock absorbers, the main damping characteristic is defined by the oil flow going through the piston assembly. Combining it with the FSD technology, Koni added a special valve, which controls an oil flow parallel to the one going through the piston rod. This parallel oil flow is closed by the FSD technology, giving a rise in damping force almost linear to the time that the piston is moving in one direction. Put simply: the FSD system is a hydraulic amplifier that delays the build up of pressure.
The Koni FSD dampers are now included in the esseesse kits for the Abarth 500C and Abarth Punto Evo.
Available now from the Abarthisti ShopAbarthisti members wishing to buy the dampers separately can now buy them from
Abarthisti, and we've secured a number of these kits at a special price.
A full set of four dampers for the Abarth 500 normally retails at £572 + VAT = £686. However, we've negotiated a special deal that allows us to offer the kit for just
£560 inc. VAT – a saving of over £120!
