The way the nose divides the airstream,the flow down the top and side,their respective velocities may be closely matched.If that is true then you'll have a nice clean separation to the turbulent wake without counter-rotating attached vortices at each side.So maybe on account of that they skip the spill plates, figuring the pilot chutes will find good air for which to yank the parachutes out of the packs and not just get slammed into the track.
I think we'll all suspect you've got some separation just behind the backlight but it sounds like the rulebook says you can't touch that area,and there's plenty of room for re-attachment,so with the exception of the small burble,the boot will be clean.
It would be nice if the body manufacturerer could provide you with a center of pressure location to compare to the center of gravity.You might want to run the spill plates just to have some weather-vane back there.If you somehow lost traction under power and one wrinkle-wall was centrifugally larger than the other,the rear end could try and steer into the smaller tire ( I don't know how effective the little drag tires are at the front for steering )and if you were getting crosswise,the weathervane might help coax the tail back,keeping you out of the guardrail.
That makes sense, think what were likely to do is make the spill plates ready to fit and test the car, if its not nice to drive the fit them to try. But were going from this body below so believe me this new body will be like a Rolls Royce!!
