Can anyone tell me what the appropriate size wheel caps are for the 21” rims? I’ve had an issue with fitment in the past and recently lost a wheel cap. I had the 69mm wheel caps whose lips fit over the bore but I noticed a used RS7 on the lot with these that fit right in. Wondering if anyone can give me insight so I can address this issue once and for all. Attached is a photo of what seems to be the appropriate wheel cap. A
