M4 F82. What is the wheel centre cap size?

[michaelw3628]

eBay, BMW parts on eBay and other comments on forums seem to confuse.
Some say the centre caps are 65mm. Some say 68mm.

Can this be confirmed by anyone with 437M standard M4 wheels please?
(I don’t have the car yet so I can’t check myself)

I've just checked mine and they are 68mm.

Great. Thanks. I’ve ordered 65mm
