Original Equipment shocks or struts supplied on new cars from the factory are designed with the inevitable compromise among handling, ride comfort and cost. Tune them for optimum handling, and ride quality usually suffers. Focus solely on comfort, and suddenly your car handles more like your parent’s old 70s Buick than the modern sports car you enjoy driving along the twisty back roads on your way home from work. For many applications, you can find aftermarket dampers that focus more on one of these two priorities, but there is still some trade-off in one area to get more of the other.
KONI engineers have been working on a solution that avoids the normal compromises existing between ride comfort and road handling, with their unique Frequency Selective Damping (FSD) shocks and struts. To get a better understanding of the impact KONI FSD Dampers have on a vehicle’s ride quality and handling, The Tire Rack team conducted a Real World Road Ride and Performance Track Drive with three of our 2004 BMW 330Ci Coupes. All three vehicles retained the factory BMW suspension components (with approx. 20,000 miles of use), and we left one vehicle equipped with the used O.E. dampers. On the second vehicle we replaced the O.E. dampers with new KONI Sport adjustable dampers. The third 330Ci was equipped with new KONI FSD units in place of the O.E. dampers.
