It looks like the rear toe "Para" has not been adjusted and you'll most likely need to move a shim from the left trailing arm to the right trailing arm to set the centre line thrust angle "Parallellsme" to near 0.00. At your reading of -0.26 reading, the rear will induce steering to the right.
It would feel better after because your front geometry settings were likely out because of the front Toe "Para" from the steering rack replacement.
If on lowered springs, fill the fuel tank half full before the next geometry (alignment) is done, or if on original springs, full with fuel/ add weight at the front so the chassis is 135-145mm from the floor. (There's an original dmc service bulletin for this)
Keep up the good work Domi
