i have eibach prokits and tokcio adjustables on my car, truthfully i wasnt really all that impressed with the suspension setup. I've maybe used the adjustability option twice. It definetly makes a difference in ride quality. One cool thing about having the adjustables for us FWD guys is that you can stiffen up the rear end of the car and loosen up the front... therefore the front tires stay planted somewhat more at the track... heh...IMO i'd see what else is out there suspension wise if it was me... the tokico just didnt do it for me
