The 550i wheels look great. And I was going to chime in that it's probably not a good idea to put wheels on a car that weighs 2,000 pounds more than the one they were designed for.

So I went to the intergoogle to get better numbers, and it looks like the GVWR (for which I'll assume the wheels were designed to) is not that different between the two cars. About 5400 lbs vs. 6000 lbs.

Probably not a bad idea after all.
