Hi tasdrouille.
my car has an Cd of 0.31, no bad, but also no good.
The opel has spold a lot hours in wind tunnel and the effects of this one they can are visible in some elements of car.
Rounded rear wheel arc (the profile), fill gapping in the front car, mirriors ect...
Although this one, the drag coefficient is "high".
So, I think that high drag contribution source is the rear end of car.
months ago I have applyed the wool tufts to look the rear flow in the rear windows.
Only detachments present is located between the rear windows and the decklid in a small bubble.
