With that spring beam that is not a joint.
Would it be safey to say the effective lenght of the wishbone is reduced as the wheel moves up and down?
The movement is in bending and not rotation.
So the effective pivot point is further away from the chassis.
Very good engineering. I couldnt imagine what they are trying to do and their confidence in it not breaking from fatigue.
Makes you wonder if they even need an anti roll spring with this design.
