I thought I'd go ahead and morph the C-pillars and trailing edges together, transitioning the tumblehome into a more semi-circular, half-body section with infinite transverse pressure bleed.
In the photo, that rear wing opening is actually 'closed' off with plexiglass. Dead air pools inside, between the flying buttresses and rear 'wing'.
The overhead wing extension forces the air off the roof to follow more of a 'Kamm' contour, sequestering any potential turbulence below it. A captured separation bubble dragged along with the car.
She could pull 100-mph in 5th-gear. Before the mods, 93-mph was the top speed, and that was in 3rd-gear, @ redline. 82-mpg @ 55-mph was the best I ever saw.

PS, you can see how I abandoned the Ford Mustang GT-type diffuser opening.
