Action 4 solid (Non quick release) mount?
I use my Action 4 in a rally car that means it experiences huge vibrations. My previous camera (Drift Ghost S) had a 1/4-20 mount right on the camera and there was no significant visible vibration in the shot (https://youtu.be/1LMfIAxeb0E) but moving to the Action 4 and its Quick release magnet/clips on the same mount I get lots of camera shake (https://youtu.be/NAo_pgmkUsk).
I don't want to turn the in-camera stability on because I much prefer the car interior is locked and the outside moves, I think it conveys the experience better. Having stability turns on makes everything 'floaty'.
Are there any good cages or rigs that I'm not finding in my searches with a solid 1/4-20 mount? They all seem to assume you're going to keep using the quick release adapters.
