The rulings on Q&A seem to indicate that the only reason something can touch the floor is for feedback, and even then, it's limited. If you put a ramp on the floor, you'll be called on <R06>.

As for specific heights, the bumpers have to be in the bumper zone (Section 8.2) and the trailer hitch has to be at a certain height.
