Panda, I have seen Kahns on an X5 , they look really good. Your picture is a little off scale , expect 20's to look smaller relative to the car.

Bro , there is a picture of a black X5 with cahns on in the item description ... http://cgi.ebay.com.au/ws/eBayISAPI....DER:SIMPLEITEM

Also the rims you are looking at are the RSC's , the RSD's are a six spoke.
