Knuckle has Ackermann adjustment built in

With certain suspension geometry at high steering angles it could happen that the steering wheel is locking up at the end and driver needs to apply some force to flip it to other side

which results in lower current demands and operation stability against huge drive pressures

which allows to change suspension stiffness and handling very quickly without changing the spring and messing up ride heights
