I dug into those PNs a little further, and according to Real OEM, the front sport pads are only to be used in conjunction with rotor numbers 34112283385 and 34112283386, which are the stock rotors that come on our cars. So far so good.

However, the rear sport pads are only to be used in conjunction with rotor numbers 34212283387 and 34212283388, which are different than the PNs for the rear rotors on our cars. The PNs for our rear rotors are 34112283801 and 34112283802.

Do you happen to know what the difference between xxx387/388 and xxx801/802 might be?
Thought the stock front discs were PNs:
34 11 2 283 801
34 11 2 283 802

and the rears are:
34 11 2 283 803
34 11 2 283 804

New ones that are to be used in conjunction with the 'sports' pads
34 11 2 283 385
34 11 2 283 386
34 11 2 283 387
34 11 2 283 388
