What rear diff & drive shafts are big engine people runn

What rear diff and drive shafts are people with 300bhp and over running?
We have found the 325i shafts snap with the v8 and some aggressive driving. I'm looking to run nearer the 500bhp and not sure what route to go.

The easy answer is a Z3M back end, but they are super rare and expensive if they do appear.

I've seen people weld in the back of a 5 series and cut the shafts, but I'd rather not run chopped shafts as I've snapped them in the past.

What do you s62 guys use?

If you are tuning 5 stude up front you should be able to run an e28 535 rear sub frame at the back by nodding the sub frame but leaving the rest unmodified
