For most Mini Z wheels you will need an adapter piece to fill the larger bearing hole with. I don't have any links, but have seen some floating around. I think you also need to grind off some on the inside to get the offset right so it would tuck under the body.
The new AWD Mini Z wheels use a double flat shaft, not a single flat like the Xmods have. Other than that the Mini Z AWD wheels would fit if you mod the shafts with a file for it to slide on.
