As many have found out, at about -2° rear camber and you will run out of toe-in adjustment with the OE toe arms. (At -2.1° rear camber my toe adjustment was maxed out to give zero rear toe.) I made my arms OE length so still had this issue with version 1. I have now made a version 2 that is 3 mm longer to give me some more toe adjustment at my desired rear camber setting. I was able to extract the ball joints and reuse them but the the swaged material had to be machined away rendering the version 1 parts scrap.
