The difference between an aero shape, and one which isn't, has to do largely with how this air is managed after it makes it past the "Fattest" part of the car. More aero shapes tend to come together gradually after this fat part thus allowing the air to make a gradual transition to what it was doing before you violated it by ramming through it at high speed.
So bottom line, your Cube creation does very little to ease this transition. Any thing the air tabs may do to "Break the Vacuum" will be more than off set by the drag created in producing the effect.
Air tabs may have some effect on Very specific automobile shapes, these shapes would be ones which the flow separation occurs due to the rear slope of the vehicle being just a bit too much for the flow to remain attached. These vehicles are not common, and your Cube is clearly far outside this group.
You have a wicked cool car though which is maximized for interior space for the size that it is. Enjoy it just the same.

I forgot about this thread for a little while!
I've been doing research on "Cube" sites for suspension lowering and such. Also seeing if I can get my hands on some genuine Japanese parts for it like the side mirrors for instance. They are small and sleek on the Japan/UK versions which is tons better than the elephant ears on the US versions.
Anyway, I wouldn't say that I was misconceived about the VG's and what they can or can't do for the Cube. I know there's no way I can eliminate the drag at the back, but if they help in the slightest bit if at all, I'm fine with that.
I can however reduce the drag. In doing so I plan on lowering the Cube 2 inches (the kit drops the front 2", the rear 1.75"), extend the air dam an inch or two which will incorporate spats/deflectors for the front wheels, put spats in the back for the rear wheels, and do some sort of grill block.
The thing is, I already had the VG's and I couldn't see the point of wasting money on returning them, so I just said the heck with it and installed them today. The way the ridges line up on the roof, I had no choice but to only use 8 of the 10 supplied VG's. You'll see what I'm talking about when you see the pics below. I also plan on purchasing one of those "Shark Fin Antenna's" to replace the stock one, and I'll most likely be getting rid of the Sirius/XM Radio altogether as they have a very small music selection that is constantly repeated and sounds like crap. Half the time, it has the sound quality of an AM tuner! I just stream Soma.FM off my iPhone via Bluetooth on my stereo.
I'll take better pics with my SLR later today.
