I think the EDC is what's holding them up. I've seen PSS10's for sale on E-bay Europe, but no one seems to have it here. I'm in the same situation as you. I have no need for double adjustable suspension. At this point, I'd be happy with some Koni Yellow's and H&R springs.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
