I think mine must be the Mindtrain version?
It mounts with 4 bolts from underneath and the center rail rests on the top surface of the decklid.
They don't rattle, but they do vibrate visibly, no noise.
The center rail has a rubber cover(split fuel line) to keep from rubbing the deck paint.
Downside is there is no easy way to clean the deck surface with them mounted, they have to be removed.
