My first thought: fantastic!

That was my second thought.

Third thought: I look at the "step" from the OEM spoiler down to the tail, and it appears it was done on purpose so as not to cover up the center-mounted brake light. I do wonder about flow separation at that point though. I'd definitely want to tuft it to see the effect on flow on the tail.

Bottom angle looks OK to me. My own experimenting showed that there's not likely going to be attached flow on the bottom of the tail, regardless of how gentle the angle of its rise - unless there's a full belly pan ahead of it anyway.

I'm really looking forward to hearing about the project & results from the builder!
