I think your reading comprehension skills need work:

1) You said that larger diameter rotors are frequently thicker than smaller diameter rotors
2) I measured rotors of different diameters and found them to be of substantially the same thickness and claimed that your assertion was incorrect.
3) You then measured a bunch of rotors of the same diameter, and...
4) You concluded that rotors of different diameter must be thicker.

In order to prove that larger diameter rotors are thicker than their smaller diameter counterparts, you'd actually have to measure the thickness of rotors with two different diameters, like I did. The only thing you've shown is that you don't know how to think logically...
