I did not add any sort of proportioning valve and didn't suffer any adverse consequences.
PCA Club Race E-Stock cars all run stock Carrera brakes, with different pads and fluid of course. Plus lots of fresh air cooling. And removal of the proportioning valve, which was probably something the Porsche attorneys made them put in. And they hold up.

I think the combination of thicker front rotors for better heat sink plus the bigger rear pistons to move some of the braking action to the rear is a nice step up in overall braking.
