No they do not work on the rear, rears are larger, but definitely on the front. I have them and as I mentioned Mike Drew (do you know of Mike?) worked with Centric/Stop Tech to build these for our cars because so many owners could not find replacement rotors. Mike has them his GF's car and also Chuck Engles has them. There are a fair number of other owners, I just can't name them. There is discussion back in 2017-2019 on the detomasolist about these rotors. Here's a snippet from that discussion: "Centric offers a dizzying array of options, starting with a plain, standard OEM-style Mustang rotor, all the way to a cross-drilled, slotted, cryogenically treated rotor (slotting makes them handed, with different part number for left and right)".
I spent a bunch of time trying to find the slotted, and cross drilled versions and was unsuccessful. When I bought these rotors I paid about $50 a piece. I spoke directly with the support people at Centric/StopTech and they could not direct me to the cross drilled or slotted versions, so I just got the standard surface, but they are vented and a fair improvement over the OEM solid rotors. The part number I posted above is the only one I could find.
Here is a picture of the slotted vented rotor that Mike put on his girlfriends car.
