Wow Randy, you're getting some "tuff love" here, but I think you know it's all intended to be constructive.
From directly behind the car, it looks like a giant center stop light (at least in the photo) when the roadster already has a pretty big one to start with.
Also IMO painting it red sort of makes it look more like a Tuner Boyz add on wing, rather than a "Porsche Like" whale tail.
I would give serious thought to losing the taped on chrome wheel well moldings too.
In the end though, it boils down to what "YOU" want. So as Jimmy Hendricks once said, "Let your Freak Flag Fly"!! I did, and I couldn't be more satisfied with the mod's that I made to my car.
