Define "problems" For the purposes of my experimenting, I considered separation to be a problem.

FYI, I don't think my tuft testing revealed any separated flow on the boat tail -- except where I expected to see it, such as on the bottom aft of the rear control arms (which extend into free flow), and aft of the un-faired tires.

There were definitely areas of increased turbulence. EG. the driver's side of the car showed more, compared to the passenger side (which I attributed to the driver's side only mirror).
