Steel wheel, SBP

From just what I can see the rotor assembly looks just like mine. I have a feeling it is the way the aftermarket wheels are made with a one fits most concept stamping using different dies before the stud holes are drilled. Your factory wheel has four nubs to hold on the small wheel cover and the aftermarket only has three, is that correct?

I really don't see a problem with the way the wheel is centered. In your first group of pictures you only have one lug nut installed and the wheel is resting on the studs so it makes it look worse than it really is. Looks like a pretty decent fit on the disc hub.

Yep probably a shared basic design, maybe different dimensions when it comes to the rotor itself.
It is a good fit on the front hub at the centre section that protrudes through the wheel is longer than on the rear so it does locate inside the wheel.

Here is the pic of the rear drum.
Also a pic of the US wheel mounted properly from earlier today.
It does seem to fit well, centres on the studs but the centre hole is too far outboard for the axle to reach through it.
I am just concerned that not having the inner ring seat on the hub/drum and not locating in the centre hole on the rear may be dangerous. Keeping in mind that this car is never taken to the strip but is used regularly on the road.
