Also, my X5 has the adaptive xenon headlights already; can I simply upgrade the lens only to get the clear Euro look, or do I have to buy the whole headlight assembly? Sorry for all the questions, but I'm quickly becomming addicted to this forum. Thanks again for the help. Don

Don no problem, and you are welcome here. I have done ALL my mods through this website, hence I have become a premier member. The information collected here to assist me is totally worth the $30 donation! Anyways, yes, the center console is a PITA but, its actually not that bad (torx screws hold it in). Follow the step by step instructions from the main page. The other pieces do snap out, however I recommend you use a plastic tool to do it, not metal. Regarding the headlights: depending on the date of manufacturing, they can be opened, cleared and have AEs installed to get the look you want. There are also 4 or 5 articles on the main page that you need to understand.

To be more specific; 275/40/R20 front, 315/35/R20 rear.

Eibach doesn't make anything lower than the Pro-Kit springs which drops it 1.2 from stock. If I can get my car 1 more inch lower without dropping KW V3 Coilover money, I'd be happy.

I also have the staggered set up with the 315 tyres on the rear. My BMW service guys keep my pressure at 40psi on all four tyres. I havent had any problems either.
