After driving about 320 miles with mods, I must say that if there was any gain, it is not showing up at all, I'm getting precisely same economy as I did before, good part is that I'm not loosing any economy either, only thing I could notice was tiny bit less wind noise and different airflow behind of the car, but there just was no any change in fuel consumption.

So to get mods work, more work is needed at planning and designing, maybe underside is more important than top side.

At 50MPH or less there really has no effect, could be that at faster speeds there has been some effect.

So next will be making underside flat and hoping that to bring some change that could be noticed.

To get 59MPG instead of ~53MPG seem to be a lot harder than what one might first think, even conditions were better, but still no help.
