Sorry, joining the party late...

That's a rule of thumb for the
initial transition. If you taper gradually (ie curve), you can apparently go up to 22* with attached flow (assuming the upstream flow is clean).

Also, I was told by MetroMPG that the transition from the top to the side should be rounded, which i haven't figured out yet. Otherwise (correct me if im wrong MetroMPG) it would create vortices (spelling?) in that area.

Yes. The images Cd made would yield better results than the initial mockup - glad to hear those are being copied. You want an organic shape so pressure recovery is gradual, not hard corners which could trip the flow and cause early separation.
The exception is the very rear surface (what I call the transom - where the tail lights go). You can chop that off clean and have hard corners there.
