When the KONI FSD came out, it revolutionized sporty daily driving. KONI is famous for adjustability in their shocks and struts, and the FSD (short for Frequency Select Damping) was able to adjust stiffness and responsiveness based on the vibration frequency of the road. The Frequency Select Damping technology features special internal valving that is meant to increase or decrease the strength of the dampers depending on the type of vibration going through the car. This made for a smooth luxurious ride over harsh roads where NVH was very high. When the road transitioned to something smoother with less harshness and vibration, the dampers were able to tighten up and provide a responsive and sporty handling experience. KONI has combined this famous FSD technology with the very popular KONI Special dampers to create KONI Special ACTIVE, a next generation damper system that builds on this no-compromise approach.
KONI Special ACTIVE replaces the KONI Gold FSD as the next generation of the technology, and in doing so also supersedes some KONI Sports as well. The Special ACTIVE is designed to be a do-all replacement, providing high levels of sporty handling without the need for manual adjustability. As you can see above, the adjustability on the Special ACTIVE happens during rebound, exactly like the KONI Sports but with less knobs. One major bonus is price, as the KONI Special ACTIVE dampers will be available at a much lower price than the outgoing FSD’s.
You’ll notice in the graph above the fat range that these can cover between low and high rebound force, which is impressive considering these aren’t electronic in any way. It’s so effective that many OE manufacturers are embracing the FSD technology found in KONI Special ACTIVE dampers and utilizing them in their factory setups. Names on that list include Mercedes-Benz, Jeep, Alfa-Romeo, FIAT, Ferrari, and Lamborghini.
If you have an electronic adjustable damper system in your car, or have had one previously, you’ll probably be familiar with the occasional problems they have. With the Special ACTIVE line, KONI is able to do away with all the complicated switches and solenoids to maintain a completely hydro-mechanical approach.
KONI Special ACTIVE are good to use with the lowering springs of your choice, we recommend H&R springs available on eEuroparts.com due to their progressive spring rate and Made-In-Germany high quality. Just be wary that KONI suggests not to drop lower than 1.25 and a maximum around 1.5in, otherwise you lose the benefits of the FSD ride. If you are a commuter that enjoys a smooth ride, with the occasional canyon run or autocross mixed in, these are for you.
