I like mine. Perfect drop height for my sedan. Haven't had any problems until now, but I believe its an installation problem and not a worksmaship problem.
Just my $0.02
I have them and they are perfect. No probs whatsoever. I think the drop is more than 1.5 though, I measured 2" in the front and 2.25" in the back after installation. Check it out, click my sig.
Heard nothing but praise about these springs; the drop is decent, and the ride is very nice. As far as a camber kit, the general consensus is that Ingalls is the way to go.
