Maplewood Derby Car Rules & Specs

Eligibility

Anyone 21 years of age or older may enter.

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

Fees

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.

Awards

SPEED AWARDS

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.

DERBY CAR SHOW

An additional prize will be awarded for “Creative Car.” Buckets will be placed in front of each car in the derby car show. The winner will be determined by the amount of tickets placed in their bucket. Participants and spectators will be able to purchase raffle tickets into the buckets of their favorite cars.

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!

MATERIALS
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. 

WEIGHT
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.

SIZE
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.

WHEELS AND AXLES
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.

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

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