I was tooling today and found a dual bolt pattern C7 hub, and that paired with a set of readily available GM calipers can be a great option, just need to firm up a rotor.
Are those the CPP hubs? If so, just be aware they don't have the ABS tone ring in them even if they look to have the rubber cover. I talked to them at SEMA last year and I guess the extra steps and machining to get the dual pattern make it impossible to put the tone rings on. Or something like that.
