I had seen some reported failures of the samberg subframe camber rings breaking off. This was mainly due to other root causes such as the front camber bolts loosening up and allowing movement. I requested that Ronin beef up mine with some extra welds (Thanks Ronin!) and they provided. They put some extra beads around the perimeter of the ring.
In addition, I etched in some lines on the back faces of the bolt face to help "grab" the metal on the subframe. When this gets tightened down it should help hold the alignment during hard driving/bumps.
