It is said that a too hard body is not good. A reason is for a maker to perform shock absorption considered for safety.

A body will transmit various information to each part, if rigidity improves. But if body reinforcement is actually performed, wages will become a large sum for reinforcing roll bar spot increase, reliance board reinforcement, etc.

Also it is difficult to imagine what effect it induces. Then, the epoch-making body reinforcement item which can be felt at low cost was developed.

This new reinforcement method makes high rigidity feel simply, so that it reverses old common sense. The car which performed urethane body reinforcement can feel the difference, when it get in and departs, you feel a motion of a car. The car which has constructed the roll cage etc. is still more effective. Although there is a difference in the ratio of an effect also by the new car or the old vehicle, rigidity is raised certainly.
