How to Build the Fastest Pinewood Derby Car

Below are the regulations most Pinewood Derbies follow, referred to as the “Rules in the Box.” It’s very important to follow these rules because if even one is broken, you’ll have a sad kid on your hands and lots of wasted time and energy. Not all Pinewood Derbies are the same so make sure to check with your local Scout District/Council rules to see if anything is different.

  1. Car Specifications: Width: 2-3/4”; Length: 7”; Weight: Maximum of 5 Ounces; Width between wheels: 1-3/4”
  2. The car must have been made during the current year (year in which derby is being held). Cannot use previous years cars.
  3. Wheel bearings, washers, and bushings are prohibited.
  4. The car shall not ride on springs.
  5. Only official Cub Scout Grand Prix Pinewood Derby wheels and axles are permitted.
  6. Only dry lubricant is permitted.
  7. Details, such as steering wheel and driver are permissible as long as these details do not exceed the maximum length, width and weight specifications.
  8. The car must be free-wheeling, with no starting devices.
  9. Each car must pass inspection by the official inspection committee before it may compete.
  10. If, at registration, a car does not pass inspection, the owner will be informed of the reason for failure and will be given time within the official weigh-in time period to make the adjustment.

After final approval, cars will not be re-inspected unless the car is damaged in handling or in a race. Plus: Check out some brilliant woodworking tips for beginners here.

Bake the block

Wood holds water, and water adds weight. We want weight, but we want the weight where it’s most beneficial. Pre-heat your oven to 250 degrees, then bake your block for 2 hours. All the water evaporates, allowing more control during the next few steps.
