It's been discussed here and on "xbimmers" and I think a couple people might be behind the scenes looking at 1" spacers and things like that. I know in the Porsche community, doing mild off-roading in Cayenne's is becoming a thing. Only a matter of time until it gets onto X5's I would think. I don't do any real off road stuff in mine but I live in the country on a crappy dirt road and also being a Michigander I would love to take the X5 onto the dunes and what not some day. I have been researching other things I can do while I'm waiting for some kind of 1" or something to come out.....

- Switching to 18" rims to increase side wall height
- Custom fab belly pan
- Possible front guard/light bar of some sort
- Rear swing away carrier integrated into the trailer hitch
- Custom roof basket-esque thing
- On and on and on. Haha!

I think the biggest draw back of our X5's over the Cayenne for example is the AWD system. Porsche allows for diff locking and varying suspension settings which is huge right out of the gate. Unless someone can hack the computer for the transfer case I don't think there is a way to drive all 4 wheels at the same time 100% of the time. I may be wrong but I haven't seen anything that says otherwise.

All that being said; if you just want to hit some mild trails and bum around the mountains throw on a bit more of an aggressive tread tire and have at it. There are a couple people on here that do stuff like that with pretty much stock X5's.
