Make sure your Carrera race track is exciting and varied by installing several lane changes. These extension tracks force the two opponents to change tracks. But be careful! Accidents often happen when racing paths cross. If both vehicles drive through the lane change at the same time, collision action is guaranteed. So you have to keep an eye on where your opponent is right now. Put your foot to the floor or slow things down just in time. The set contains two lane changes. You can assemble the parts directly behind each other for extra action. Both track sections have a length of 228 mm, a width of 114 mm and are on a scale of 1:43. They are suitable for the Carrera DIGITAL 143, Carrera GO!!! and Carrera GO!!! PLUS.
