Z4 E85 2004 Alloy centre caps - what size/make?

[ajs01]

hello - can anyone please advise what size I need to get to replace the centre caps of my alloys. I am changing from the split rim alloys to 107's. Do you guys replace with oem or aftermarket ?
thanks in advance

I recently bought some for my 108s.
As already mentioned they're 68mm. I'm not sure if I can post the link to where I bought mine from, but if you put the part number into eBay, plenty will show up.

Just be careful when jet washing them...
Either back up when doing so or turn the power off!
