M3 straight control arms- what toe-in is necessary for -1.1 camber?

The only fault after the M3 control arms installment (and camber inrease from -0.6 to -1.1 degrees) is that the steering wheel does not come back from the full left and right positions.

Do I have to decrease the toe-in from 0.9mm to 0.6mm or 0.3mm?

What about the rear toe-in?

Thanks a lot in advance.

Turned out, after a week, the M3 arms settled, and MUCH- the toe at the front went from +0.9/+0.9mm to +1.9/+2.6!!!

Now did the following adjustments:

FRONT:
camber
-0.8/-1.1 degrees (seems to be settled further)
toe:
+0.3/+0.3mm

REAR:
camber:
-1.8/-1.9 degrees
toe:
+0.6/+0.6mm

Seems good now, the steering is returning from full left/right with no issues now, the self-centering became a little weaker and the car is overally more qute and settled- not that nervious like before the adjustment.
