Update: I went with the machining and had new holes drilled into the hubs. The pictures below speak for themselves.
I noticed that the the hub is about the same weight as the stock one, and regret not weighing everything out right now. This is contrary to SuperNow's claims that their product is lighter... oh well.
I am also a little concerned about the strength of these hubs since the lip where the wheel studs go in has a smaller thickness than the stock setup. I am pleased however with the fact that the races are MUCH easier to reach compared to the stock design.
The installed system w/ wheel on. Those are the long gorilla nuts. The aforementioned spacer is also behind the wheel.
