From marko's 2nd picture, if the 60/40 "front" side door is already open, and you try to open
the van's passenger door at the same time, the back edge of the passenger door will collide with
and probably scrape the heck out of the ground effects panel on the 60/40 front half of the side door.
The same would likely happen if you opened the 60/40 front side door and tried to close the (open)
passenger door past it. In either case, the point of contact and damage would be low down on
either door, near the bottom rear edge of the passenger door or the front of the ground effects panel.
The kit is designed to reduce drag on the outside of the body by "smoothing" the silhouette of the van's
sides, making it more aerodynamic. It also purports to increase downward force on the vehicle, by
creating a partial vacuum underneath the van, similar to what you'd see on some types of racing cars,
although I'd question it's usefulness on a large, already quite heavy, van. I think my manual mentions it
too, and I don't have it installed (like marko's first pic) either.
