Hi I bought a send of a6 2009 rs4 alloys I thought they would of fitted my 2011 a4 is there anything u can by for them to fit r do I just need to by an other set thabks

 

You'll have to look up the center-bore of the centering ring and the bolt pattern of both vehicles and compare. I had a beautiful set of RS4 replicas from my 2003 A6 that I planned to use on my 2011 A4 and they did not fit. Sold them cheap...heartbreaking.
