Ahhh, I can't prove a thing, . Look at azraelswrd's post because it is helpful regarding how to do a coast-down test. My problem is, there is *no* place I can think of in LA to do this test. Because I don't have a "boxy" car like a Scion xB or a Jeep, I can't even perceive any road-stability benefit. If I could perceive increased road stability in a cross-wind, that would imply aero-improvement to me. Here is what they look like (I still need to add some below the window, just lazy as usual) :



As others have done, you could "make your own". If you are leery of the aesthetics, you could use business card magnets to move them around. A possible defect to magnet attachment is that I think the VG needs to be symmetrical in relation to the wind. The Evo-style VGs are angled to the wind. If those were magnetically placed, they would probably be "pushed" into line. Also, for side mounting, I wouldn't recommend magnets because gravity is "pulling" them down, increasing chance of loss and/or misalignment.
