4wd: torque split front-to-rear other than 50/50?

[NaN]

I've finally had the time to do some testing.

Running with the TC on Australian Countryside, I've tested with torque-split 1.0 and 0.0 and center diff anti-slip set to 0.0. The difference is clearly there. 0.0 (FWD) is understeering at any time, while 1.0 (RWD) allows induce oversteer by flooring the throttle.

I think the issue is engine power vs tire grip. We might have too much (side) grip, especially on gravel.
