ZU-Rims fit any axle, drum or disc but of course you need the correct wheel-nuts.
I bought a set when the first came out (that was about 2006-7) and ran them for many years, an excellent quality wheel which does not give any problems with balancing.
I only replaced them as after about 8-years the paint was starting to mark in a couple of places (don't get me wrong, they weren't scabby but just chipped in one or two places) so as they would have needed a re-paint at some point in the future I decided to fit Sawtooth alloys instead (for the more OE look). Off came the ZU's and they were sold on.
