You can see how the driveshafts and turnbuckles are swept backwards, indicating that the wheels are much further back than the original position.
After looking through the pictures a bit more carefully, I think that what I wrote before about increased wheelbase, is not accurate.
In the end John Pape's comment might be the only correct reason they used the susp. arms inverted.
