Question about brake rotors

[Full_of_fit]

Hello,
I hope everyone is doing well. This may seem like a dumb question but what is the difference between bmw f80 oem vs oes parts?

I ask because I am looking at brake rotors on eBay, from the same seller. Just a note I need to stay BMW friendly due to my extended warranty.

Here is the first set of rotors:

Here is the second:

When I asked the seller if they are both OEM parts he said yes. When I asked him why the price difference he said the first posting price has just not been updated, however from the links you can even see that page description is different. He asked from my VIN and said either would work.
Of course the first answer someone may have is, one is for ceramic brakes, however I just have a Competition Package WITHOUT Ceramic brakes.
I would just like some help to see if there is something I am overlooking that would justify such a price difference.
Thank you in advance for your time, insight and help,
Ian

Yes I have read the before, I should have been more specific. The seller says they are both OEM, so I curious what would cause the price difference.

I guess their price update failed. The cheaper one says Genuine BMW with part numbers. The more expensive implies OEM (says OES) which would likely be Brembo branded. I’d go with Genuine all day long. If they arrive and don’t have BMW part numbers on the box you can complain.

Awesome man thank you! I thought I was seeing things when I saw the BMW
ones were cheaper. I’m going to buy them now since the price they are posting is the price 👍
