Most of the setup sheets on durango are showing 4mm trailing with very few running 3mm trailing. I somehow managed to get mine on 2mm trailing from when it was built and realised and went to 4mm trailing and the difference is massive so much more controlable and i even turned off the -15%exp i had on the steering.
Also whats been important is to get the spacer washers infront or behind the hub dependant on what trailing your running which is shown on the setup page on durango.
