These knuckles have an "in between" position hole from the original ones in the kit. When using 2 or 4 degree caster the position of the outer steering joint moves back and this not only increases bump steer, but it also makes the steering ackerman more agressive, making the car a little harder to drive hard. With these knuckles, the steering is much smoother and the ackerman is closer to the original position when running Zero caster tower.
