I've put adjustable Koni's on several of my cars over the years (the first was in 1980!) and they have always been excellent for me. That is why I ordered the Koni/BAT combination for my Contour SE a year ago without any hesitation. That is also why I ordered the new Koni Sport Suspension kit for my SVT (from AJ-USA) before it was released. Well, it was that AND the special pre-release pricing; $650.97 with free shipping. The price is now $665.97 and the shipping is still free (see attached link), but several people here on the CEG have reported that the kit is back-ordered, so if you are in a hurry......
