Aero wizards - what do you see as the plusses/minuses of these two?
Here are my poorly educated guesses:
Blue line is intended to be horizontal. Would allow a fairly clean view out the rear window. I think I prefer this version but consider the purple line one also.
Purple line would add downforce?? And I believe generating that downforce creates its own additional amount of drag? Or are the added downforce and drag very small due to relatively low pressure in the area just above the trunk lid?

Visibility out the window is essential, and your purple line would block more than a Kamm back, probably. A horizontal spoiler would be something like the XR4TI double-spoiler thing of yore (unique look). I'm still looking beyond the bumper. I have another build of the spoiler good to go. I'll test it soon, maybe tomorrow or Wednesday. Hope I don't get a fix it ticket. I'll post photos in a minute.
