Tungsten is approximately 1.7 times denser than lead and 3.2 times denser than the zinc (lead-freei weight often used on pinewood derby cars, thus it allows a tremendous amount of freedom in the car design especially for speed by allowing the builder to place a large amount of weight in a small, aerodynamic area.
