Car hooks up, chirps into second in WOT, is almost neutral (slight understeer) with controlable drifting.

Why higher front pressure than rear? That's never been a BMW spec - always higher in the rear. Higher pressures reduce compliance and grip. The sharper handling felt from higher pressure comes at a cost and is often confused for grip (based on decades of observing the Internet
).
If you run the rears higher than the fronts you may dial out the remaining understeer (although slight understeer bias is almost certainly safer for a "dad car" not always driven with a high degree of focus.
Accident avoidance in the rain while out for groceries, for instance, would be better if you scrubbed a little rather than spun.
