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

      If you are using 3/8" round weights, drill your 3/8" weight holes before cutting out the rest of the car because it is easier to hold the full block. Always use a clamp to hold your block before drilling or cutting. Safety First!

      wheels Tip

      Spin each wheel on a polished axle with graphite and count the number of revolutions. If a wheel wobbles, try spinning it again. If it still wobbles, get another wheel that does not wobble.
