Its not just that, its also the ease of adjustment. AGX's you had to stick your hand through the back wheels, or carry a tiny screwdriver around. Im not saying that going from setting 12 to 14 makes a difference but 12 to 24 surely does a little. I mean even my g/f who doesn't even know what suspension is or does, or what a muffler is, thought she needed new blinker fluid when I told her she did (really) - made a comment about the car riding different when I was usually rolling around town on 6 and 10 in the rear and went to 24 and 30.
