That was a stock 950 Adv. hub. I don't recall waht I did for rotor width spacing, but I made custom axle spacers and then used some little spacers under the stock SM non-foating calipers to make the stock SM rotors fit with full brake pad bite. As I recall, these spacers were just 3mm thick.
So, stock 950 Adv. 19" wheel, stock 950SM brakes and rotors with some minor spacers.
