Looking at two of the images posted about the launch, the rear strut of the rear suspension upper A-arm, seems to be pushed towards the back of the car. to my untrained eye, it looks like a bit of an afterthought with that kink in it.
Why might they have done this? To act as some sort of flow conditioner? I know it will move as the suspension travels, but could that still be used to stop air flow "bleeding" into the space between the beam wing and main wing?
Could they have moved the wheel forward, this reducing the wheelbase by a couple of centimeters?
Could it just be a packaging issue? They needed to move to attach to the gearbox mount in a certain place or to avoid some bodywork?
