I need to buy new blank rotors, no slots or drilling, for use with my base C6 calipers. Last time I ordered:

19175115/2/Right Delco Durastop rotor/@$43.99
19175116/2/Left Delco Durastop rotor/@$43.99

But I don't recall if those were technically C5 rotors. My preference is to have the correctly directional vanes on each side. Looking on Rockauto, I was going to get the Centric high carbon rotors, but they only have one part number for the front which means that they aren't directionally vaned.

Rockauto lists these ACDelco part numbers for the standard C6 rotors but none of them specify L/R orientation.
19203421
19175920, 19286286
88955509
19235225

If I ordered C5 rotors last time, are the base C6 rotors available in directionally vaned versions? If not, opinions on whether I should continue with the C5 directionally vaned vs the Centric standard vaned high carbon alloy?

The front and rear C5 napa blank rotors work on the base c6 brakes.
IIRC each corner has a diff part #
Price was roughly 200 bucks for all 4

Stock C5 rotors have vanes that are directionally correct, assuming you use them in the right location. C6 JL9 rotors have no vanes, but the internal connecting posts allow bi-directional airflow.

DBA 4000 series, I guess I should say that if you get slotted they ARE directional
