well i guess i need to start a new thread... who is on koni special active? soon to be me!
Couldnt wait any longer for the Bill's to arrive. ECS had contacted me and asked if I was interested in trying the new FSD replacement/update called the Special Active. They are roughly the same in opperation just updated look and materials as well as being able to be bought individually, something I guess could not be done with the FSD's.
I spoke with Lee at Koni for about an hour before making the decision. He was very knowledgable and described in detail how the FSD tech works and how the change in spring rate, or drop due to spring rate, might affect the ride quality. I actually just found a post on mk6golf.com where someone else talked to him as well. This was almost word for word our conversation as well:
The whole thing with the FSDs is that they need to stay off the bump rubbers most of the time. They are great for stock or mild lowering springs where the car is not expected to hit the bump rubbers much. You can't just willy-nilly apply them to any springs as many springs will regularly hit or are even designed to use the bump stops as supplemental spring rates. We have great results matching them on many cars with Eibach Pro-kit lowering springs which tend to have a somewhat conservative drop.
In a nutshell, the FSD filters out short, high frequency impacts from the road surface that normally cause negative ride quality issues. When a car is low enough that it hits the bump rubbers fairly often, the FSD sees that just like a road impact and doesn't generate much damping force however normally a bump rubber impact is actually asking for more rebound damping and not less. So a car with FSDs that regularly hits the bump rubbers sharply may feel underdamped at those times. Some cars and springs rarely hit the bump rubbers and other cars (Minis, new Mustangs, Pontiac G8, Chrysler 300, etc.) hit the bump rubbers very quickly if lowered at all so those cars are recommended for FSD only on OE springs. Others (most BMWs, VWs, Audis, etc.) do great with moderate lowering and FSD. It just requires testing to confirm if that car and spring package are bump rubber impacters or not.
For cars that are lower or likely to hit the bump rubbers, then KONI Sports are always a safe bet as they could care less if you hit the bump rubber or not.

He also mentioned a recent customer, an MQB A3, who installed the special active series along with eibach pro kit and said he loved the results. He also mentioned they will soon be releasing kits for the mk7 and 7.5 with a special actives and paired springs.
SO! All that to say, I think the VWR springs/35mm drop will be a good match for the Special actives and I am looking forward to testing it out!
