3.0 upgrade to 4.6is, 4.8is

[X5Ghost]

Hello X5er's
I'm new to the X5 forum but familiar forums as I belong to the Acura one. I finally bought my 3.0 X5 and join the many satisfied owners. I have a quick question to kick off my project on the X5. With all due respect to the 4.4, 4.6, and 4.8 owners, I want to upgrade my 3.0 look to the 4.6is look but with the lovely 4.8is wheels. I just could not afford the 4.6 or 4.8 with the options and milage I was looking for. So I settled for a 3.0 hoping to upgrade it. Besides, gas prices weren't helping either. The Q: I can not find 4.8is wheels anywhere other that the dealer who is asking $775 for the fronts and $805 for the rear ea.? Has anyone attempted to chnge their 3.0 to look like 4.6 or 4.8? any info regarding these topics is greatly appreciated. Looking forward to many many posts.
