When these cracks first appeared in the '05 models, ( I had them on my 05RT) I wondered if it was from some old habits of folks/techs using 105Nm torque values of the previous series of drives on the new EVO drives. Basically doubling the value cannot be a good thing on that spider.
I had to pull the manual out on a fairly competent wrench who was still using that value on the 60Nm required torque. Steel bolts in a steel flange vs, steel bolts in that aluminum spider. He said I was wrong and he used the 105 setting on "everything"
The original BMWNA recommended fix for mine was to file the cracks smooth as no one had the equipment or knowledge on how to exchange the flange at the time

It just goes to show what the truth is with these so called "perfeshunals" and "eggspurts".
