I should elaborate more on the AWD M3 I built in 1990:
The BMW 325iX AWD sedan had a 70/30 split, with a rear bias. The transfer case, and ancillaries was patterned after Audi's Quattro. In fact, you are correct- the weakest link on the iX, is the front drive portion.
I'll be honest- BMW could not support the monstrous torque this iron-block six produced([email protected]/396lb/ft twist). When all options (Audi/Subaru/Lancia/Nissan) were evaluated- I went with the Audi CS AWD drivetrain, with heavy
mods. The modifications included refabricated drive, halfshafts that alone cost almost $10k. We were glad to go with the Teutonic Audi drive system- a very robust, stout unit, even in stock form.
Its no wonder why Audi won the world rally championships had-over-fist, in the early Eighties.

I shoehorned a KKK turbo M88(euro-spec M6) into one, back in 1990. The customer had pockets up to his ears, and also wanted his M3 to have AWD. So, I welded a clip from the 325iX first, then mated the drivetrain to the 418bhp M88. The torque(396/lb.ft) was so extreme- the chassis was
twisted like a wrung-out towel.

You're not shitting us??
I've always heard the front differential in the iX is a weak point and couldn't handle too much power. An M20 no problem but a 400+ hp motor?
