Maplewood Derby Car Rules & Specs


Anyone 21 years of age or older may enter.

Previously raced or entered Pinewood Derby cars from other events may not be entered.


An entry fee of $30 per car is required for registration (shipping not included). There’s no limit to the number of cars registered to an individual or business. Each registration includes a Pinewood Derby car kit. (You will be contacted to arrange for pick-up of your kit after you have purchased your ticket)



First, second and third place prizes will be awarded to the fastest three cars.  To be considered eligible for “fastest car” awards, cars must meet ALL technical specs outlined below.


An additional prize will be awarded for “Creative Car.” Participants and spectators will be able to purchase raffle tickets to vote for their favorite cars. There will be a winner for the car with the most votes, and a random drawing for an additional prize.

Technical Specs

We don't want to get too technical. And while this is meant to be fun, there are some rules. Keep in mind that we’ll have some inspectors at race day check-in who will evaluate each car’s adherence to the technical standards. This is supposed to be fun, but play fair!

All cars entered shall be constructed from the Pinewood Derby kit that’s purchased from Partners In Housing. The block of wood from the kit, or portions thereof, must be prominent in the design. “Add-ons” of plastic, metal, decorations, natural materials*, etc. are allowed and encouraged. Above all, have fun with your design. Be creative. Funny’s good, too. 

Race cars may weigh no more than five (5) ounces (total weight) as determined on the official scale during race day inspection. Weight may be added to the car and will be considered part of the car for purposes of all measurements. If you add weight, make sure it’s secure. Think glue.

Race cars may be no longer than 7 inches, nor wider than 2.75 inches, nor taller than 3 inches, per the official gauges during race day inspection. Underside clearance of 3/8 (0.375) inches is recommended so your car will run down the racetrack easily.

The car must roll on the wheels and axles from the kit. Firmly fix the axles to the car body. Wheel treatment (hub and tread smoothing/polishing) may not result in substantial removal of mass nor in reducing tread (track contact) width from the original kit wheels. You can paint the wheels.

No engines, CO2 cartridges, or leftover fireworks. Just gravity.

Only dry/powdered lubricants such as graphite may be used.
