Hey rabbit congrats on the new ride.
I'll throw a few pics from my other opst of my old 2002 Sienna red X5 with 22's for your reference. They were not staggered but looked great back in 2001!
Now I'm on to a set of the wonderul 87's for our new 2006 X5. The 22's added quite a bit of weight which as you know wears on things like brake pads and rotors and most of the front end bits. Also kills acceleration a little too. Personally I think most of this negative impact is trivial but here we are modding our X5's with CAI's for a fe mroe horses so....
Anyway, check the pics of our old X5 with 22's. I think I ran 275's all around.
Good luck and enjoy!
