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.
