The Multi-Lane Speed Box offers the tools for thrilling stunts and side-by-side races. Kids can take their track building to new heights by making any table, chair or shelf into a gravity drop stunt. Set up a downhill race with the built-in clamp and use the 4-lane fair-start gate to kick it off! Get creative with gravity drops for epic action! Turn the box over and use the 4-lane jump on the bottom as an awesome finishing stunt!
