Hey everyone. I tried searching but everyone seem to have hids on the 5th gen and not on the 4th gen. I have a couple of questions, if i get a d2s ballast and bulbs, how can it fit into my 4th gen headlight housing? also, i just installed a hid on my friends cl and the beam is not centered and shoots EVERYWHERE. Did anyone have that similar problem? I know projectors are the way to go but has anyone tried it in their stock headlight housing? Thanks for the valuable info.
