The more your pine car weighs, the faster it will go on a downhill ramp. Most rules specify a 5 oz. maximum weight. Most Pinewood Derby cars weigh between 1.5 oz and 3.5 oz (depending on design) without weights so a car may need 3.5 oz or more of additional weight.
When your pine car is completed, it should balance 1" to 1 1/2" in front of the rear axle. Position the weights to adjust the car's balance. To check the balance, place a pencil across the car and move it forward and back until the car balances on it.
Our tungsten weights are available in a variety of shapes.
