2nd Gen RX7 rear camber issue

I'm having trouble getting anything more than about 1.2* of negative camber in the back of my FC (note, I am trying to increase negative camber, ideally to around 2*). I have both the AWR independent camber adjusters as well as the vertical adjustable link that Mazdatrix sells (forget who makes it).

With the vertical link fully extended (so it is at its longest) and the independent links also fully extended (so there is virtually no thread showing above the lock nut) I am still stuck at -1.2* on the passenger side and -0.9* on the drivers side.

Any ideas on what I could do to increase this? Are my adjustments correct?

You are going the right way. You have to drop the inner pickup points to get more camber. It makes no sense you can not get at least 2.5. What is your ride height at the rockers. If you are down to the 5" min it should be no problem. All the bushings in the uprights (hub carrier) centered and in good shape?
