I am not familiar with the 30D or its brakes, but...

I was told that the X4 M40i front brakes were "borrowed" from the (bigger) X5. It should be simple enough to compare parts numbers for the two of them, and but I never bothered.

I will say this that it took a few miles before the braking was consistent and confident. Maybe as much as 1,000 miles. Or maybe I just got comfortable/used to them at that point. I dunno.

The brakes are extremely dusty, more so than any other Bimmer I have had the pleasure to drive. But make no mistake, these brakes work very well on this heavy car.
