A 360 camera on the ceiling is interesting. What do you mean by "top brace"? Model Y has a single pane of glass, so the camera would need to stick to it.
Unfortunately due to the strong summer heat overhead, suction mount won't work, and even 3M VHB tape won't hold for long in my experience, with using a front dashcam in other cars.
