You know why the diffuser center channel curves upwards? because it doesn't need to be flat anymore. No reason to keep up air velocity after air has reached behind the axles. It doesn't do anything to the downforce or liminar profile on the vehicle by extending it. Instead, use the high pressure air stream made up of slower moving air molecules and divert them to the area that greatly suffers from wake and vacuum which is directly behind the trunk and centerline of the vehicle.
