Don't forget that on the 8ight, any of them, the left rear and right front lower shock mount screws back out. I think it's XRAY that makes a reverse thread for this exact problem. The set screw in the bottom of the arm isn't even enough for some reason. I even tried putting a screw in the next hole that overlapped the shock screw and it still backed out. Until I get those reverse threaded screws I just added a generous amount of glue in addition to the extra screw and it's holding together well. Keep your car really clean and that will help you notice these things that go wrong earlier and more often.
