Benito, see this response . And in addition, it is half caged with a 4 point setup (so NO not my street car).
Nate, you may be onto something with how much I am tightening these down...........I initially had issues with getting the upper shock nut tightened as it continuously became loose after 100 miles or so and I could never tighten it (or may be user error as far as tightening is concerned)
Ever seen a break like this Nate??
