To that kind of driving yes I am sure a higher lockup is needed than what the m performance diff provides. Someone can research it but IIRC it's only approx 30%

Er, not quite. BMW wasn't able to supply manual-transmission cars and the traction-control software on the paddle-shift cars in these shots kept getting in the way. The inside rear wheel would lift, the standard, 25 percent limited-slip differential would do its best and then the electronic stability program would shut the power down before both rear wheels got properly lit up.
"It's like driving a computer."

Californian ex-motocross star Riley Harper, whose function seems be about equal parts ringmaster, choreographer and general go-to guy, explained: "We flew in a BMW factory technician to re-write the software - which helped, but not enough."

Finally Drift Mob's own MacGyver, known only as Zach, opened the differential housing on one of the cars and welded the crown wheel and pinion gears to lock it solid. Then he fitted a rough-and-ready additional handbrake, plumbed directly into the rear brake callipers, and that did the trick, despite the concerns of the BMW egghead that the car's sophisticated electronics would not take kindly to such cavalier treatment.

What I mean is, the commercial itself is for the LSD. I think it would have been a nice touch.

Hmm philosophically if this is what matters to you, maybe an STI or Evo is better. RWD is just fun to drive, period. It may not be the fastest off the line but I feel that the M235i is meant to be enjoyed in classic BMW form.
