Still curious about the separation edge along that curved opening though at the rear and if it’ll improve anything

Probably doing boat tail foam wedges behind the tires though this weekend
1) Once all the streamlining ahead of the rear separation line is performed, the drag, from thereon, will drop in direct proportion to a reduction in the wake area.
2) Knowing the Cd, just choose a target drag coefficient you desire.
3) Whatever that percentage difference is, that drag will be delivered along with a tail with a wake area the same percentage smaller than the original wake area.
4) It's basically that straightforward.
