With this set, you can greatly expand your racetrack. A good racetrack naturally includes many curves, lane changes, and switches. But the most important aspect is the connections. This is where the straight tracks come into play. With this set, you receive six tracks in a 1:43 scale, all of which integrate well. To allow for flexibility in your setup, the tracks come in different lengths. Three pieces are 100 mm long, and there are three additional pieces measuring 114 mm. With this set, you can extend your Carrera Digital 143, Carrera GO, or Carrera GO Plus by a total of 642 mm. This way, you and your friends can experience pure racing fun!.
