The bottom lead cylinders weigh .7 oz and are 1 5/8" long!

Tungsten gives you four advantages:

  1. You can pack more weight in a smaller area giving you more flexibility in your car design.

  2. You can place weight exactly where you need it for maximum speed.

  3. Tungsten has the added advantage of being non-toxic, so you do not need gloves to handle it.

  4. Diameter is 3/8". Just drill a 3/8" hole and slide them in. Use wood putty or glue
    to seal the hole.

      Tips & Hints

      Before cutting your car, use a straight edge to draw lines down the center lengthwise and widthwise across your car. Then draw your car design template over these straight lines. The template and straight lines help guide your cutting on both sides of the car so everything is square.

      Spin each wheel and axle and count the number of revolutions. Keep the slowest pair together and replace them with a faster set.

      Be sure any decorative parts are super glued into place! If you lose a piece off your car it will affect the weight of the car, resulting in loss of inertia, decreasing your speed.
