As for focusing I'd get the tuning kit from retrofit source. They are basically ring shaped spacers that you stack to get the focus you want. I personally put the headlight housing (minus the lens), and left the projector assembly loose so I could just plug it in and try it, then add/remove without full install/disassembly every time. If I remember correctly I didn't use any.

I did have to grind down the lens, which I made a thread about. How to grind down a projector lens to fit the holder
Yes, the paper spacers were purchased from TRS to get a guestimate of 1st iteration of 3D printed adapter's offset dimension. I know the drill here but thanks.

The E90 LCI adaptive lens holder has a weird 3 finger holding setup. The paper spacers and slightly undersize STi-R lens will fall through the holder. Thus, my adapter holds the undersize STi-R lens AND has the 3 keyways on it to be held by the 3 fingers.
