Thanks for the great pics and information. Like "jditom" I am wondering about the spacers. My BMW dealer is quoting an 18" package with the Dunlop Winter Sport M2 tires (265/55-18) and BMW rims, but did not mention anything about spacers.

I had a 4.4 and traded it for the 4.8is, and I'm debating whether or not to put a winter package on it, since it only needs to get me to work and back. The roads are generally plowed soon after a snowfall, although still snow covered and slippery. Was thinking maybe all the traction control thingy's might get the job done. On the other hand, I hate to subject the 20" rims to Wisconsin winters.
