pucho,
You're right about the servo saver, although a lot of racers (myself included) mostly tightened the built in savers down, to create consistent steering.
As for the dogbone and their angles, sems to be sorted out, just about 90 degree...
Arms and links are either straight or have a slight angle.
And the diff is especially designed to be really closed. And thus pretty maintenance free.
As for the shocks. They will not be using the internal adjustable ones, but a regular design.
