These babies will be just right perfect

That is exactly what I got on my 19.
19's are little rough and stiff but 18 is the perfect size and perfect look .
However, you will need longer bolts.
For some reason I was not able to get long enough OEM bolts at dealer.
So I picked up a set of aftermarket bolts though I do not prefer use aftermarket stuff.
I guess all C219 wheels are perfect fitment not sure about C218
