How to tell S5 N/A rotors...?

How would one distinguish between 9.7 CR rotors and 9.0 CR rotors?

The Recessed area of each rotor face.
The S5 NA Rotors have this area machined, and the marks left are quite different from the cast surface of the S4

Also by the price being charged; the high comp. rotors are in high demand and therefore the rotary salvage people charge much more for them. I have had to pay $150 apiece for them used.

My S5 TII 9.0 CR rotors were machined as well though... How would I tell the difference between them?

well, you'd need them side by side, but wouldn't the N/A rotors have a more shallow recess on each face than the T2?
