half to one turn on the bottom which you think are related to chassis
tweak. e.g. bulk head screws etc.

setting board. Front and rear’ shock tower now support your car.

rear gently then tighten top deck’s screws gently. (DO NOT TIGHTEN
SCREWS HARD AT THIS STAGE)

again then retighten all screws. This time you can tighten with your
maximum power.
