The math I did to get that is:
380x30 = 11,400
400x36 = 14,400
26.3% difference
370x24 = 8,880
380x30 = 11,400
28.3% difference
..........
If we look at the weights, they are lighter than expected in relation to the increased size.
Fronts are only 22.8% heaver
Rears are only 21.5% heaver

Remember when calculating the size of a 3d disk (Cylinder) you need to use pi multiplied by the radius squared, times the height. not just multiply the diameter and height.
Volume = 3.14~ * r^2 * H
OGm2 Front disk volume (assuming these are actually just cylinders) : V≈3.4×10^6
2NH Front disk volume : V≈4.52×10^6
difference in volume of the hypothetical disks is 32%
This is just for fun, the above numbers are pretty pointless since we dont know:
Alloy used in both disks
Hat dimensions of both disks
Vane design/count of both disks
Space cut for airflow in both disks (drilled holes, and the dimensions of the vanes for airflow in the center of the disk)
etc...
