We now have Koni FSD (Frequency Selective Damping) set for A5 chassis GolfJetta The FSD patented technology provides a firm ride on long bumps and corners for control, and a soft ride on expansion joints and rough roads for comfort.
The FSD has an extra valve that controls an oil flow parrallel to the piston assembly that opens over high frequency inputs, such as expansion joints, providing a smooth ride. The valve closes over low frequency imputs such as cornering transitions, providing better control. The valving is integrated into the strut, is non-electonic, and does not require any external sensors or adjustments.
