yeah, it's not the arms that are the problem - that's kind of a lame suggestion on their part.
the camber adjustment bolts - which connect the lower control arm to the hub - are eccentric. the problem with these bolts is that over time, they rust, and the eccentric lobe on the bolt corrodes away, making them either totally frozen in the bushing, or not eccentric anymore, which means no adjustment can be done.
easiest solution? buy a new pair of bolts from BMW. i think they're ~$10/each.
