What sometimes is hard to understand is that as your camber link pivot spacing decreases vs. the lower arm pivot spacing,yes it increases camber gain as the 2 are swinging different arcs but it also creates a bind. This bind is what decreases roll and you really wont experience as much camber gain as expected because the cars suspension will not compress or roll as much as a longer link and now will drive the tire into the ground creating more traction to that wheel. If you lower the inboard or raise the outboard pivot, roll is reduced but weight transfer to the tire is reduced and will actually loosen up that end of the car and reduce traction. I lower the camber link on the tower when I want to reduce side bite and raise it to increase it. But if the car rolls too much, I shorten the link and/or go to heavier sway bars. I hope that makes sense. I hate typing.
