The Hot Wheels® Track Builder System offers the ultimate track experience for kids by allowing them to design, create and customize their very own track challenges. Using a variety of stunts, layouts and essential pieces that kids can be the master of their own track. With the Side Shot Launcher™, you've got one car on the track and one on the launcher and everyone on course for a turbo-charged collision! A special trigger side launch allows one car to be racing along the track while another one barrels at full-speed in a different direction. Will they crash in the middle or race across? If you can dream it, you can build it with Track Builder!
