There, camber is set so the tires become flush with the road under cornering loads. But that's under limit of traction conditions and the angle is set for each track specifically. At road speeds, that kind of excess is useless. All it does is make the inside wear out faster.

My best guess is that, given they do not even clear the sheet metal standing still, that is the only way for the car to remain usable (and YMM really V).
