I have my ute setup exactly how I want it as far as wheel/tire combination and fender clearance, but I want to upgrade my brakes. Right now I'm using the stock disc setup which uses a very small solid disc and small caliper mounting bolt spacing. I've already made coilovers out of the struts I'm using and don't really want to change struts.

What I plan to do is have new hubs made up that will have the outer face of the hub 8mm inwards to compensate for S13 discs between the hub and wheel. This way the wheels will be in the same spot, Then make up so brackets for the calipers.

What I want to know is if there's something I'm not seeing like problems with extra stress on wheel bearings or something along those lines and I'm open to suggestions.

Here's old pics of the current setup before I cut it up and made coilovers out of the struts:
