yeh i had to grind out the bulb housing in order to fit the HID bulbs into those projectors, but the out come of them is amazing ill post pics later on this week. Whoever told you that they weren't made for HID kits is right but with a little modification with a dremel (making the opening more circular and wider) they fit fine, and they have that beautiful white-aqua-purple horizon line bmw's and acuras alike are famous for, not to mention they look great with Halo's, and give out ridiculous amounts of light without blinding :-)
i sell these kits too 6k, 8k, 10k, and 12k - everything for 300 so nice
like i said ill get pics...
