A special material made from steel is attached on the front of Bumper to make it immortal to the collision. Therefore, bumper can hit the car as many as it can as long the car not cross the border or in other word, the end of the track.

When bumper hit the car, the collision will be presented in sound and particle emission. The armour indicator will be reduced depends on how hard is the collision.
