Ok here is the deal... I have/had an F13 M6 and F10 M5. I replaced both sets of stock wheels with HRE's as most of you know and have both stockers nicely wrapped up and stacked in my garage.
Here is my dilemma: one stack of 4 is the M5 wheels and the other is the M6 set. I know there are small differences but I cant exactly tell from the naked eye so I figured Id ask here if anyone knows the exact differences and maybe even part numbers.
I have sold the M5 wheels but am not sure which stack is the right one and I dont want to deliver the wrong set and then find out after he mounts them that they do not fit.
I know I know, idiot
Edit these are the 343 style wheels 20's.
