I know that when my castor was at 1.6 before my UCA's I did not have this. So the increase in castor must move it more backwards I guess.
It doesn't rub at full turn, only while turning and hitting bumps or going up my angled drive way with my wheels turned.
+ caster moves the tire forward, - caster moves it back. The further back it is, the better is steering is, however you need to find a compromise.
My caster is 3.4 degrees with the body mount chopped and pinched. With 285's I still rub a little on the rear mount when flexed but not bad.
In your case I'd try another degree forward from 2.3 to 3.3. Also get them to dial that camber to 0 or slightly negative.
I've tried it all. 5 degrees is too much and you'll hit the front plastic, 2.6 is too far back, so I've found the best success with 3.2-4 degrees caster.
