I have Eibach Pro-Kit springs and Koni FSD (Kit 2100-4001) dampers on my GT Sport and it's much more comfortable than the standard shocks with Eibach Sportline springs that I have on my Eddie. You won't lower your GTI but it will handle better and be more comfortable.
The Koni FSD kit I got is the non-GTI, so it's a bit more comfortable for that as well.
Sorry for dredging up such an old thread, but I can't PM yet to ask questions of other members.
Shoduchi (or anyone else): Are there any drawbacks to the Koni FSDs compared to the std Sachs dampers?
How do they compare for general handling/ride/braking/turn-in?
I'm currently considering suspension options for my (~60,000 mile) Mk5 GTI. I'm considering the VWR dampers, FSDs or Koni Sport. Preferably with std springs, but would consider new springs as long as they do not lower the car much (I have driveway clearance issues). I would like to preserve the general GTI feel and handling, but with a better ride. Specifically, to smooth out the jiggliness and generally unsettled feel of the std set up on our poor roads.
Cheers
