Enter the Ultimate Ride Booster game and select the mode: stunts and highway racing. The track will be unusual; at a certain distance there are various obstacles on it: springboards on which the car jumps into a round arch, red giant hammers, each of which can throw your car far to the side of the road. Each collision will affect the appearance of the car and it will become more difficult for you to control it. So make quick repairs by clicking on the wrench car icon in Ultimate Ride Booster.
