Nick,
I am planning this mod on the wife's new-to-us X5 (we pick it up tommorow). Have you ordered your kit yet? I have heard good things about the JLEVI kit. I have not done an angel eye install myself, but have done a few mod's to my e46 and consider myself to be deciently handy when it comes to this kind of stuff. Since we're both in Cow-town, when my kit comes in we could get together to put them in our X5's...
Did you say you needed brakes done too?
