exactly. Don't listen to the others. Some 18s look small. Example: the foregestar 18s look great cause the spokes go right to the edge of the wheel unlike the Apex wheels (look side by side you'll see). My Works, being a stepped lip are really an 18" center section so they don't look big and in fact kinda look smaller than OEM GTS wheels at times. 20s are def a no no, they just look too big and belong on a 5 series IMO not a performance car.
