Pinewood Derby Weights
Stick-on, Screw-on or Round Tungsten and Zinc Weights
You must add weight to your pinewood derby car to be competitive.
Gravity is moving your car down the track. The more weight your car has, the more inertia it has and the faster it will race to the finish line.
Pinewood derby weights come in a variety of sizes, such as 3/8" round cylinder weights and 1/4" cube weights that can be hidden inside the car, stick-on wieghts that can be placed anywhere on your car or screw-on weights tyipically screwed to the bottom of your car.
Weights also come in a variety of materials, such as zinc, lead and tungsten. These materials have different densities and costs. Lead is dense and inexpensive but it is toxic so we do not sell lead weights. Zinc is inexpensive and non-toxic but it is not very dense so it takes up lots of space on your car. Tungsten is non-toxic and 1.7 times denser than lead so it is a good choice, but it is expensive.
Advantages and More Information on Tungsten Weights
The maximum weight limit for a pinewood derby car is 5 ounces.
Plan on adding 2 to 3.5 oz of weight to your car, depending on your car design and the weight of your pine wood block. A chunky car design has more wood so it needs less weight. A thin, small car design has less wood so it needs more weight.
To get the exact weight you need, use stick-on weights, tungsten putty or tungsten BB's to add small incremental weight anywhere on your car.
Consider purchasing your own scale to avoid last minute adjustments on race day. We offer a large platform scale with a stainless steel tray and a handy little portable pocket scale accurate to .001 oz!

Why Tungsten Weights are better
Tungsten gives you an advantage because it is about 1.8 times more dense than lead...
Since pinewood derby cars are so small it is important to place weight exactly where you need it.
The single tungsten cylinder on top (.5oz) weighs nearly the same as the three zinc cylinders (.75oz) on the bottom.
This gives you more flexibility in your car design,

Tips & Hints
Lead is denser than zinc but lead is toxic, so we do not recommend handling it. Use non-toxic weights like zinc or tungsten.
Wood filler is your best friend when it comes to building a pinewood derby car. Use wood filler to fill holes, gouges and other cutting mistakes. You can even use it to add a bubble, racer cockpit, spoiler, etc.
If it isn't explicitly stated in the rules, then you can do it. If you have questions about your rules, ask your race manager, since all races have different rules.
