I completely agree with you on that point, would have been much MUCH better if the spokes went straight to the barrel. With that said though, I still think that they do look pretty good. Also, alot of people say that the spokes stick out past the edge of the rim and knock the rim because of that. However, as you can see, they are at the edge of the rim.
It's all personal preference but I don't think they'd look bad on a Z, especially in flat black. And especially when you consider the price and good offset, kind of hard to find when looking for Z wheels
