I ordered rear rotors for a 2003 M3.
My buddy with the 330 came by today, I verified he has 300mm rotors which means he does not have m sport. Coincidentally, he needs pads and rotors on his car so I’m going to use his garbage ones for fitment testing anyway.
I will also take measurements of the rotor and get back tomorrow.

It’s clear they’re not worried about a crack developing at a hole and growing to the free edge because there’s probably a crack already there from machining down the rotor OD!
I’ll look to see if I can find the e46 M3 rear pad profile and its radial depth. You’d think I’d know because I took delivery of 03.5 in August ‘03 but added an AP Racing brake kit within the first 8 months of ownership.
