Indeed that sounds exactly like BMW. 265 rear width is not enough for 420+ hp at all, esp with RWD. Why does BMW do this??? Are they too cheap? I can't figure out the reason. This beast could handle 295/305 easily on the rear.
Also, 19s should be std but I think $ is the simple reason they wont be. If they were, 20s would be the only upgrade option and that is probably just a bit too much for an OEM. Hence we get 18s std, ugh.
BTW: I think the OP list is bogus, just my opinion.
