Previous owner of mine swapped the fronts out for EBC 2 piece floating rotors. Still stock rears.

Strongly doubt they are warped, likely just have pad deposits. Bed them in again and save your money.

Or get them turned/machined if that doesn't do it. A shop that turns rotors will probably be able to tell you if they are actually warped or worn too thin.

BMW dealers automatic response is usually "replace all rotors and pads", they're not into troubleshooting and steer towards the easier "replace everything" option.

I don't think you can machine drilled rotors.

Looked online because I was curious. Apparently you can.

You can, I've had it done. Not all shops have the equipment for it.
