Thank you. The fronts are both ET 48. However the rears are ET 45. What does ET 45 mean? As I'm a noob to all this wheels stuff.
So it should bolt right up without any mods?

BMW uses "ET _ _" or sometimes "IS _ _" which represents the wheel's offset. The blank spaces will contain a number that represents millimeters. So ET45 means that the wheel has a 45mm offset.

The link in Smokey53's post above goes into greater detail as to what wheel offset is.
