I am not an aero person, but this iteration looks like it would have less frontal downforce then the wedge type nose of the Riley, and at the same time would flow more or better air to the rear deck, slot and wing, seemingy like you would have to run less rear downforce to balance the car, and I have an overall loss of downforce? Also, how have these things escaped BHF's? I do not follow grandam so I don't know, but I guess they have escaped having the side-on lifting seen in LMP's?
The R8 is an Audi, which means they are sandbagging
