As the uglyback was sacrificed and there is a lot of place between the C pillar and the trunk cover, I used a free quarter of hour this evening... I got a small piece of coroplast and taped it at the end of the roof (c-pillar), with a smaller piece put vertically to give the primary one a "good" angle.
Here are three pictures :
I'll have to work on the visibility but I think it will be better than with the ugglyback, I won't hesitate to shorten the miniback if I can't improve visibility enough only by working on the vertical piece.
Hope this will improve the aero. As tomorrow is a day off, I'll be able to test it only Monday morning when I'll go to work...
Denis.
