    can anyone confirm or deny that this looks ok or not.

    that is fine, they remove material and drill holes on it like that to balance the wheel. these SC wheels spin at 70-80,000 + rpm's so the balancing has to be perfect.

    C1 or C3 wheel? Don't forget to use that little spacer on the shaft right underneath the nut when installing it.

    be careful not to over tighten the nut the shafts are not that strong.

    It's no comparison in quality/craftsmanship between the ET/Riva wheels and then the R&D wheels, no spacers either.
