Thanks for the informative reply OtherDave. I am also considering Koni Yellows with Ground Controls or H&R sport springs. Where can I buy NT450s??? They are hard to find, maybe discontinued. I have two new ones, and want to match them rather than buy a new set of four. My question about the camber adjustability on the Tanabe Sustec SS was since it has an upper mount with a camber plate, does the camber plate eliminate the need for camber kit? I live in Santa Rosa, by the way.
