Do you have any history with this company? I m not familiar with jxb
If the rain ever quits, I'll be replacing mine. ordered the JXB with both the street and track bushing a while back, when they were on sale.
During my last oil change on my '15 HC M6, I just happened to have a brand new inspection mirror, so check a few normally well hidden things, and center carrier bushing was obviously dry-rotted. Last drive a few weeks back, before all this damn rain, having a little fun up in the mexican part of our county, the bushing tore free. Had to limp home to a think-thunk-thunk soundtrack
kinda looks like this now:

edit: there are a couple other companies making replacement parts, but don't know if any are making them for our cars yet. I only know of one person who had an issue with the JXB [in this asylum with the rest of us], and if I remember right it was just failure to tighten the bolts sufficiently
