Im looking for a set of center lock nuts m72 for OZ 13" wheels. The taper is 45 degrees * 10,4mm.

the initial plan was to make them ourselves, but as time is running short we want to buy them instead. Any suggestions on were we might order them from??

I can't help you on your nuts but may i ask what exact wheel model do you have?

I have searched OZ and i can't find any 13" wheels on their website.

Im sure a quick call to the OZ distributor will turn up results. I never knew OZ had center locks. All the 13's i have seen are 4 lug.

We at Riteh Racing Team have OZ Superleggera 13" they produce these wheel in versions for 4 lug or center lock.

Contact OZ Italy directly is the best option in my opinion

You can easily turn them on the lathe and thread them, and drill a hole in them for a cotter pin. That is what our team did this year.

Well, after searching for some time it seems like there is impossible to buy them, so we´ll make them ourselves. An already packed schedule gets even more packed, but who needs sleep right??

Regarding were to find these wheels, Id say give OZ Italy a call, as its much faster than spending hours searching the internet.
