3) the 286mm vented and 300mm vented use the same caliper, but different caliper carriers
4) 286mm solid, 286mm vented, and 300mm vented use the same pads
5) I think that no rear brakes are compatible with the 318ti/Z3 hub; you can swap in the ///M roadster/coupe rotors, but it requires replacing the wheel hub; I was told, but never confirmed, that E46 rear bares would fit if the parking brake shoes are removed (I can't confirm nor deny this).
7) I'm not sure that rotors will actually be swappable between models as the hub/offset might be different. For example, although the Z4 2.5 and the Z3 2.3/2.5i/2.8 used the same calipers & carriers for the 286mm setting, the rotors p/n for the Z4 is different form the Z3...
8) If I may suggest, I would actually reverse the chart in the sense of putting the rotor size as title and the compatible models below. |
Thank you for the detailed input. I will add that the E46 323 sedan has the smaller brakes vs the coupe/convert. As far as wheel size, I wonder if a 15" wheel would fit under a E46 325 300 mm rotor? Didn't 15" come stock or was that just in the early E46 base sedans? To be safe, for sure use 17's with any E36 M3, M coupe, M roady, 330 front brake upgrade. *Some* 16's fit, but it's not worth the effort imo.
So the E46 325 with the 300 mm vented has the exact same caliper as all E36 325/328 models? Good info. I am currently looking at a great condition used set of E46 325 calipers/carriers for under $100. I assume I will just order the 300 mm vented E46 blanks for front rotors. By assume, I mean I doubt the 286 mm vented fit right?
EDIT: It seems the 323ci coupes do not use the 300 mm larger front rotors. The only 323 E46 models to do so are the convertible and the touring.
EDIT(2): I took your advice and totally redid the chart. This has taken me some time, so I hope all of you get some use out of it.
