I've been wondering about this for awhile now, but here is my 2¢ worth. I think the 45° NDFW is a "magic trick". When you look at the car you focus on the strangely located wheel/fender combo because the car is amazingly fast and therefore feel this is the where the speed lies. I have never seen this car live and in person, likely talking through my hat, but I believe the speed secret lies elsewhere in the car and the 45'd wheel/fender combo is just a distraction, hence the "magic trick".
We'll never know until one of two things happens: One, someone has figured out the magic in this build or two, the original builder reveals his magic (I don't see this happening). Until then, build on people, build on! The R&D continues!
