Mechie3's picture(s) of the white rear is almost a perfect shot for a blank to work with. The shot just needs to taken down a bit, a little more centered (a little to the right) and stand back about 20ft and zoom in so you don't get that camera arc. But Mechie3's picture is one of the best I have seen so far.

Here is a blank rear picture I took if someone would like a plank canvas to start from.
I have no Idea if it has the qualities the David is looking for.
My rear tires in this shot are only 225 wide on 55 offset rims.
