Each section of the track must be carefully aligned otherwise you get bumps at every section. Bumps cause cars to fly off if the COG is not properly balanced. Setup is the foundation to creating a pinewood derby car that is first on the finish line. If your setup is correct, then the rest of the upgraded parts will ALWAYS give you an edge up. If your setup is wrong, adding upgrades will probably have ZERO benefit.

As a young girl, my father and I would spend several weeks transforming a block of pine into a sleek racing car. Our school hosted a pinewood derby each Spring and it still remains one of the most memorable things my father and I did together during my childhood. He always got very passionate about our cars, tinkering with designs and strategizing over where to place the weights for speed.
Pinewood Derby Tips & Hints
The Pinewood Derby High-Speed Graphite is an odor-free, extra-fine dry powdered lubricant. So, whether you’re a seasoned pinewood derby veteran or a first-timer, remember to have fun and enjoy the process. Who knows, maybe you’ll build the fastest pinewood derby car in history and break some records along the way. The fastest pinewood derby car design is a car that is lightweight, with a pointed nose and tapered body to reduce drag. The weight should be balanced and centred, with the heaviest part of the car at the back.

Building a car is lots of fun, and the project provides the perfect opportunity for parents to make lifelong memories with their Scouts. To help everyone stay safe, monitor your Scout's use of tools, always wear goggles to protect the eyes, and don't wear loose-fitting clothing! Here’s a list of some useful safety guidelines found on the Scout Shop website. With the nail still in the drill press, round the inner face of the nail head with a file and sand it smooth. To make sure your car doesn’t exceed the weight limit, weigh all the parts before assembly. Leave a little wiggle room for paint, glue, stickers, etc.
When you’re ready to press the axle into the body, use a wheel spacer tool to be sure you don’t install it too tightly. While you can buy the tool, we quickly made one out of a scrap of metal. Keeping the tool between the body and wheel ensures you leave enough space to allow the wheel to turn freely. Spread more epoxy over the top of the weights, all the way to edges of the pocket.
Our PRO tools will save you time building your car while helping make your car faster. The PRO Driller, featured here, is just one of our many PRO Tools. Lighter wheels turn require less energy to turn them, which translates into speed. We offer lightly lathed wheels and the faster Ultra-Lite wheels (check your rules!). To get even more speed, we offer both versions in a graphite-coated version, our fastest BSA wheels. Squirt some graphite into both sides of each wheel before inserting the axle.
Your Shopping Cart is Empty
Finding the sources of friction and findingways to reduce it is the secret to a fast car. Here are some ways to reduce friction and increase speed. To design the fastest pinewood derby car at your next race, you must first understand how these cars work. The heavier your car is, the faster it’ll be, but it’s the location of the weight that makes the most difference. You can add small weights to the wood body of the car, so long as the it doesn’t exceed the total weight limit.

Testing your car before race day is also crucial, as it allows you to make any necessary adjustments and ensure that your car is running smoothly and straight. Tungsten weights are ideal for pinewood derby cars. Tungsten is about 1/3 smaller than zinc that has the same weight. Therefor, you can pack Tungsten weights in a smaller area to optimize your center of gravity to maximize inertia giving you greater speed at the finish gate.

It also messes with graphite’s natural chemistry of stacking or building of layers. I have gone over how to choose the best wheels for your car based on track conditions. Ultimately your local pack rules will tell you what wheels you are allowed to race with.
A derby race is 3 seconds in length with a top speed of 20 mph at a car’s top speed. There is out there, a pretty prominent builder site claiming that a “straight running” derby car is the fastest. A race track that never moves and maintained in perfect conditions will have different results.
The PRO Driller allows you to re-drill the axle slots, drill new axle holes, or drill axle holes to make an extended wheelbase. Our PRO Graphite, with molybdenum disulfide, has helped people win races for over 15 years. Our Track Tests show an average speed increase of 17%. Our non-hardening Tungsten Putty is ideal for getting your car up to the maximum 5.0 oz limit.
