I have never seen this wheel on a z before..can anyone help.. Datsun is imprinted on wheels....

Here they are on my 78 780

Ahh! I haven't seen any of those in decades! Those are either BWA (made in Italy in the '70s and early '80s), or one one of a couple brands of replicas made in the '80s. Since they do say Datsun on them, I'd bet on them being real BWAs. Probably 14x6. If they are true BWAs, they will use normal cone-seat lug nuts, will have tapered steel lug seat inserts, will be machine finished with clear coat, and will probably have 'BWA' lettering cast on them somewhere.

BWA were imported to the USA by Conti Enterprises, the same people who imported Ansa exhausts to the USA back then. BWAs were quite common on Fiats here in the States, but they were available for almost any car.

Ads from late '70s R&T magazines showing various widths and fitments.

thanks arne...so did they come on my z?

Well, they're on it. But they didn't come from the factory, no. Possibly dealer-installed.

i thought about changing them to a more modern look... what do you think woud look good on it.. any suggestions? thanks again

I'm not the right guy to ask. I prefer a vintage looking wheel on these cars.

Those wheels are very unique and not very common if it was me I would keep them unless you are going to restore and use original wheels. If not I am sure you could get a pretty penny for the not so common wheels and might help into getting more modern wheels. Check out Motorsport Auto for more modern wheels popular ones are Panasport and Konig wheels.

Cheers
