Absolutely don't know a lot about this even though I drive one, but I have been trying to get my head around my setup and what's possible... Don't know if this helps or not...my car is 2015 STi and this from my manual.
Symmetrical All-Wheel Drive with Driver Control Center Differential (DCCD)featuring three performance modes and six driver-selectable differential lockingsettings;
mechanical and electronically controlled limited-slip center differential;helical limited-slip front differential and TORSEN® limited-slip rear differential,steering angle input sensor; nominal torque split is 41:59
So from the feel of the car it's 41 front and 59 rear on my cars standard setup
