Hi, I bought some used winter rims from a 2009 Q5 (OEM Audi - 7J x 17 ET 37) and planned to mount them on my 2017 Q5. The required offset on the later Q5s is 39, so 2mm difference. Do I need to add spacers to clear the brake calipers etc? Is this something commonly done, or would I better off waiting to find some Audi rims with the proper offset? Thanks!
