I'm kind of over adjustable sway bars. The only really good selling point about them to me is that you might not know exactly how stiff you want your bar when you buy it, and the adjustable gives you 2 or 3 bars in one. That said, I haven't adjusted my 20-24 Whiteline RSB ecept one time, going from 22-24 when I put the heavy duty mounts on. 22mm is a pretty good size for the front bar on an Impreza.
cliff notes: Somebody buy this from John, don't make him wait around, it's a great deal. I would, but I'm holding out for my coilovers and F/R 27mm XRD bars from Whiteline.
