Daryl;
Very nice build!
In the last photo, it looks like there is a gap between the front of the spoiler and the trunk lid. If so, this will be interpreted as a "wing" since air can flow over both the top and bottom of the surface. This was pointed out to me when I posted pictures of my spoiler. I blocked the underside air flow to solve that rule interpretation.
