Once I torqued that down, quiet. Of course the harnesses themselves make noise if you don't have them buckled to the camlock, especially if you're using the eyebolts/clips.

I actually picked the GMG because I liked that it mounted on top of the strut. Even though that's a more painful install, I figured maybe it would add meaningful rigidity. All things being equal anyways. It felt like there were many very similar bars and it was easy to have decision paralysis.
