Extra Long Tracks for Easy Installation: The slot car track is 18.4 ft long, which is longer than most other products, and has a better system to lock into place and easy to assemble. In order to keep the car on the track better, we have enhanced the magnetism, but it is also important to control the speed, remember to slow down when turning. In addition, we also prepare extra brushes on the bottom of the car for you, which you can replace at any time.
