Finally, i have managed to cure the problem, the upper left rear link end was on a tad too loose, tightened it up a full rotation and it pulled the rear end of the chassis over more, still not enough to satisfy me mind you. I then looked at the rear right upper link and decided to loosen the link end one full rotation, this has fixed the problem to where I am happy. Rather than put a washer in place between the link end and the link itself i turned to using a 94mm link on the rear right upper instead of the stated 93mm link.
Now I know this is probably not what everyone would do but it has fixed my issue and I am happier now that the rear end is centrally placed over the diff.... now just need to place a washer between the shocks and shock towers to create clearance to stop them fouling on eachother and attend to the suspension itself, the axial shocks suck! Leaking already! Any recommendations Proline Powerstroke, Traxxas Big Bores, Boom Racing Type G's?
