Looks like this is something that must be checked occasionally. If the bolts come loose, then it seems like a guarantee for a failure. The teflon tape on the bolts is an option, but would this perform better than the right thread lock?
We mostly have gassers at my airfield and most are running them stock. In fact, I may be the first one to have installed the adapter. It is just so convenient, I really like it.

One thing to keep in mind when considering installing one, it moved your spinner out the thickness of the base of the adapter. This is around 3/16". I had a nice tight reveal at my spinner with my cowl on my warbird and this modification screwed that up. I may modify my stand offs to move my engine back to fix this.
