I accept this might come across as negative and I don't want to stop you adding adjustable lower links (I have them as well) but if you have excessive rear camber I think I'd prefer to know the reason why it's that way before adding something that "adjusts it out".
For example there's an increase in camber as the spring compresses (or at least there is on the TC) so maybe rule out sagging springs first ? I'd definitely go for adjustable links but it would be annoying to do all that work and then find there's something else causing the problem and it comes around to bite you later on. If the suspension is standard and rear tracking is right, then the camber should be within range.
