The two most important goals in the design of a race car
chassis are that it be lightweight and rigid.
Light weight is important to achieve the greatest
accelleration for a given engine power. Rigidity is important
to maintain precise control over the suspension geometry,
that is, to keep the wheels firmly in contact with the race
course surface. Unfortunately these two goals are often in
direct conflict. Finding the best compromise between weight
and rigidity is part of the art and science of race car engineering.
