Lets say you want to lower the RC by 2.5mm.
Lowering the arm mounts by about 1mm would do this (e.g. going from B1 to B0).
Raising the inner camber link by about 3mm would also do this (so going from hole 3 to 1 will be close as that is 2.3mm apart - you could then lower the outer ball by 0.7mm and you'd be spot on).
However moving the camber link will have more of an effect on camber gain than moving the lower arm. The lower arm position will have negligable effect on camber gain, the camber link will affect it quite a bit.
So if you wanted to lower the RC and keep as much camber gain as possible for maximum grip, you'd lower the wishbone.
If you wanted to raise the RC to keep the car flat, but add some camber gain to maintain traction, you'd lower the inner camber link which would raise the RC and add some camber gain (about half a degree on the outside wheel at full roll from 5mm RH).
