Gheez guys. In Netherlands (europe) the basic f30 is delivered on low resistance 16" rims. This is to make the car fit the the lowest emission class which has a certain taxation advantage in netherlands. 17" inch and above is optional.
The lines are delivered with 17" rims. 18" and higher is optional for the lines and expensive here.
Anyway, i ordered mine with 17" style 392 from the sportline and thats ok. Need to draw the line somewhere :-)
