about the camber shims:
better °'s
black one ( always the bigger one) below, and a silver one above : 1.0° camber
or
silver below and blue above : 0.5°
or black one below and blue above : 1.5°...

the camber adjustment isn't to use the tires flat
on the contrary , you should always have at least 0.5° camber
otherwise the tires will hook into the track which is not so good

up front: more camber gives more steering, less camber gives less steering

and rear,
more: decreases traction at the beginning and mid corner
makes the rear glide a bit in the holes/bumps, so the buggy doesn't turn over
and less increases this, to a point where the car breaks out at the rear

suspension rods in the same levelas arms, gives no change in camber
rods higher upright side, give more camber at compression of suspension/shocks
rods higher on the towers, gives more camber at decompresion of the suspension/shocks
the shorter the rods the more variation of camber one gets

did you know with more camber the suspensions work better to?
the tires driving on their sides take over some suspension work ...
