I didnt read it, but I thought that as long as one has projector type bulbs, HIDs would be fine, because of the concentration of light and the cutoff. I would get the euro ellipoids either hella or depo, that is up to you. To me,eyes are sweet, but only on the e39. I personally dont like it on the e34 and e36. It seems to fit well with the e46, but you dont have one anyways.
if you do want theeyes, ebay sells them coupled with euro ellipsoids.
