    Only if they let the midpipe sag enough that they touch the cross member plates. In my experience, even really old mid hangers still work. A very tough part. It even has rubber blocks built into it that don't let it collapse too much. My 17xk originals didn't even really need replacement, tbh.

      The front of the 2 cross member plates (even though realoem only shows 1) is what starts contacting/rattling. I have removed the front one and run without it when I got annoyed. The rear of the two cross member plates is what the hanger connects to.

      Once I got ss section 2, because the pipe diameter of ss is larger, it actually came with 1/4" spacers to put between the body and the plate to lower the plate to avoid contact.

        Just picking this up again, however does anyone know the reason for why the hangers prematurely fail when fitted the wrong way?

        Other than the fact that they have been fitted the wrong way around?

        Also can someone confirm that the hangers in the attached images are fitted the correct way?

          If the hangers are a “K” with the end toward the front of the car, this looks to be correct, as the mounting point should be a little left of center.

          This makes me want to check mine because it's news to me.
