The hudy pins are great if you want close and quick, but they have a large sticking point (30-50g per scale if you remeasure what you thought was center)

You need to balance the chassis, and also the suspension. The chassis is balanced without roll bars and equal shocks (length and tension) plus setup wheels.

The suspension is easier to do with something like the old MIP or hudy tweak board to adjust the preload on the sway bars without shocks, and then preload on the shocks.
