I'm extremely interested in this. However, just like everyone I have a few questions I was hoping you can answer for me. To my understanding the E46 had a 'facelift' after the manufacturing year of 2002. I currently have a 2004. Will installation be affected by this? How much 'abuse' can the halos take? Are they brittle? I'm just afraid I'm going to do something stupid like drop it while installing it or something... Last question, I also have xenon headlights OEM on the car arleady. Will this affect the installation? Sorry for all these questions, I just want to rather be sure than always have lingering questions in my head. Thanks in advance!
