20" rim for premium package

[SnowFlake]

i currently own a 2003 X5 Sports Package that was recently in a car accident, but all fixed and shortly will be sold

I like 20" BMW rim off 03 4.6 model and thinking of going the cheaper rout and acquiring 2002/2003 premium package and drop 4.6 20" replica rims off Ebay.

Will the suspension look lowered on the premium package over sports package with 20" rim on that car is my main concern. Does anyone own a set of 20" replica 4.6 rim from Ebay since i ma not sure of the quality of the rim.
