Welcome to the club, this is a very common thing in mustangs, I replaced my whole rear suspension even went back to stock springs once to try and figure it out, but still the infamous squat was still there, clean title, never wrecked, bumped or anything, go figure. The strange thing is I only have it on the notch and the notch is the only one I drive hard, it could be due to hard driving and racing a lot but who knows? Let us all know when you figure it out, if you do.
