I used to have a Lancia delta integrale.. That one was 4x4 with open front, cetral with 40/60 tq split and viscous lock and rear torsen. It was not unpredictable, far from it, but that is heavily influenced by the central diff... I suspect that the torsen and ACD combo would not work well. Anyway, why change from plate rear...

Im just jealous you had a Lancia Delta Integrale
The AWD in general helped predictability too. Its the RWD cars that we seem to have issues with stock torsen rear diffs. Like the RX7 and Mustangs.
But 100%, there's no reason to swap from stock diff restacked. They aren't heavy maintenance items for street cars. For track cars I would swap out to something inner coil springs rather than outer cone springs to keep more constant preload through its life but that's a different discussion.

Can you confirm if these are the same or superior to the weir plates? https://www.racingdiffs.com/collecti...34705477042338

The stock plates have alternating groove patterns for oil and to create friction. From what I've seen on the Wier kit the smooth plates just polish themselves and then its full slippery (no more LSD action). These being smooth seem like they'd do the same thing but can only speak to the Weir kit not working well.

I wasted a ton of money having to but a second diff in order to have TRE build me one good one. F**k Weir.

Overall it is a great car, but torsional stiffness is really low and body just cant handle the power and grip. Superb steering feel.
A guy on integrale forums took his shell to a place that did shell prep for Prodrive, to seamweld and strengthen the original shell, but without the cage. Many $$$ later they ended with a shell that was stiff as stock impreza shell.

It depends on your setup. In most cases we'll have inside rear lifting before we get into any appreciable wheel speed differences on the rear axle. Its possible it could help in some braking stability if one wheel locks up? Maybe? Just guessing when it would come into play.
I run a 1way both front and rear.
