Meh, I gave up on fixing those bloody retrofits.
First my two brackets on L and R sides aren't screwed in the same way, which impacted the angle of the projector, so if my low beams are on the same level, stock high beams are not. My mistake I presume, but there is no way to know before reinstalling the headlights anyways.
Second, the hotspots weren't in the center, so I had to use tiewraps around the xenon bulb back, through a hole in the back twist-on cap, attached to a bolt - with a controlled tension pulling the bulbs, the hotspots are now where they should be. On the flip side, i have exactly the same rot. aligment issue as you do now.
