You’ll absolutely see the rear settle on heavy braking with the diff. It won’t be subtle. Also, you’ll also see some push on exit so drive in harder and rotate.
i think unless you are bumping against the Nannie’s it shouldn’t make too much difference. You’ll feel that on the .2 cars the .1 cars hardly intervene as it’s only tc, not stability.

good luck getting it sorted.
