Forget eurobadgez.com. Buy your overlays from Jlevi or bimmian. Both are the same and WILL fit all the roundels on your car (steering wheel, front, back, and wheels). I had the same problem with BavAuto a long time ago and they wouldn't refund it since I had already opened it...
Just go through jlevi, you won't be disappointed! Plus, they have a million colors to choose from.
