Basic Car Specifications (for both Stock Car Series and Open Series): 

Dimensions and weights:


  • Cars must have been built using an Official BSA Pinewood Derby Kit. Width, including wheels and axles, must not exceed 2¾ inches (6.99cm).
  • Length shall not exceed 7 inches (17.78cm).
  • Weight shall not exceed 5.0 ounces (141.75 grams) measured on a scale accurate to 1/10th of an ounce. Overweight cars must be reduced to running weight or below before they can be entered.  The official race scale shall be considered final.
  • Cars must clear the center rail of the track, which is 1 5/8 inches wide by ¼ inch tall along the entire length of the car.  Minimum clearance between the bottom of the car and the bottom of the wheels shall be 3/8 of an inch to avoid contact with the tracks center guide strip.
  • No part of the car may protrude beyond the starting pin. The front edge of the car must not be more than 1 inch above the wheel lane of the track and be at least 1/2 inch wide at the center of the car.
  • Any details added must be within the length, width, and weight limits.
  • All cars must have a wheelbase no less than 4 inches (101.6 mm), with the two rear wheels being positioned directly across the body from one another and the two front wheels being positioned directly across the body from one another. A maximum allowable wheelbase shall not allow any portion of the wheels to extend beyond the front or rear of the car.
  • No part of the car or any attachment to the car may be capable of coming into contact with the track other than the wheels.


Wheels:


  • Use only Official BSA Wheels; colored wheels are permitted.

  • All lettering and numbering, both inside and outside, must remain complete and be visible.
  • The fluting and other BSA markings on the outside wheel area must remain visible. 
  • Outer wheel surface (tread area only) may be lightly sanded, shaved, or polished to remove minor surface imperfections, mold casting burrs, and correct off-center wheel bores; but total wheel diameter may not be reduced below 1.170 inches (29.72mm). Outer wheel surface must not be reshaped or have the contour changed in any way in an attempt to minimize tread contact or alter aerodynamics. 
  • The tread surface must be flat and parallel to the wheel bore.
  • Coning the hubs and truing the inside tread edge is allowed, as long as the overall wheel width is not reduced below 0.36 inches (9.14 mm). 
  • No material may be removed from the inside wheel surfaces at any point.
  • The minimum outside diameter of the wheel must be equal to or greater than 1.170 inch (29.72mm), in order to maintain the ridges on the outer edge.
  • Judges reserve the right to measure the wheel with calipers to verify dimensional compliance with official wheel size restrictions.
  • The weight of the wheel shall not be increased or decreased except where limited amounts of material are removed from the tread or inside tread edge to remove minor imperfections. No material such as glue, fingernail polish, or tape, may be added to the inside of the wheel increasing its weight.
  • Wheel Bore treatment is allowed including polishing and/or tapping. Wheel bores may not be filled and re-drilled to alter bore diameter or to achieve better fit with the axle (no material may be added to the wheels)


 STOCK CAR DIVISION:  Wheels, Axles and Suspension: 


  • The Stock Car Division is intended to maintain a level of competition of which most scouts are capable of achieving with minimal adult intervention. This division is the essence of the Pinewood Derby and in the sense of fair play we’ve kept the rules simple.  Any car that passes the basic qualifications above but doesn’t pass the Stock Car rules will be moved to the Open Stock division.
  • Only official BSA Pinewood Derby Kit wheels, either new or old style, and BSA axles may be used. Wheels may be lightly sanded to remove the mold projection. This very light sanding is the ONLY wheel modification allowed.  All markings must be intact on the inside and the outside of the wheel.  Colored BSA wheels are permitted.
  • All 4 wheels must be on the track at all times.
  • BSA axles may be polished, deburred and lubricated but must be left otherwise untouched – period.  No lubricating oil or liquid lubricant of any kind may be used. Only powdered graphite is permitted.
  • Factory axle slots must be used, but they may be trued or straightened.


OPEN STOCK DIVISION:  


  • Open Stock is an open division for parents and siblings of scouts who want to participate in the Pinewood Derby. All of the above specifications for a legal entry must be met for open stock. However, the car weight limit is extended to 15.0 ounces from the standard 5.0 ounces for the “Stock” division.


Examples of Prohibited Items which CANNOT be used:


  • Magnets, springs or suspension systems of any type.
  • Starting devices, finish line devices, propellants, or propulsion systems
  • Wet paint, or Sticky substances
  • Glass or excessively fragile parts
  • Electronic or lighting devices (if lights are on the car they must be turned off)
  • No Bearings or Solid one-piece rod-style axles
  • Axles and wheels attached to any device that mechanically alters rotation or spin.
  •  Loose objects in the car. All weight must be securely fastened or embedded in the car.


 Race Operations and Miscellaneous Rules:


  • The Cubmaster will be the official starter for each race.
  • The Cubmaster may delegate this duty to another leader as necessary during the event.
  • Race Officials will be assigned based on the volunteer pool for the event.
  • Cars will run in races of 4 cars (if a lane becomes unusable the cars per race will be adjusted accordingly)
  • Each car will run a minimum of three races.
  • Cars will alternate lanes on the track to ensure fairness.
  • Once a car has finished the last three times it will be considered eliminated and will not continue to race.
  • Finishing order will be based on electronic scoring.
  • Finishing positions for each race will be identified on the bottom of the cars by the use of color-coded stickers to be applied only by Race Officials.
  • If a car suffers a mechanical problem during a race (i.e loses an axle, breaks a wheel, etc…), the participant and/or a designated adult will have up to five minutes to fix the car. The race will NOT be rerun, nor can ongoing races be delayed.
  • If a car leaves the track during a race, the race will be rerun. If the same car leaves the track a second time during, the car will be judged “the last place” in that race.
  • If a car leaves its lane, Race Officials, at their discretion, may inspect the track and, if a track fault is found which may have caused the initial violation, the Race Officials, at their discretion, may order the race to be rerun after the track is repaired.
  • In the event of Starter interference, the race will be re-staged and rerun.
  • The track’s electronic timers will record the finishing place for all cars in each race. In the event of technical difficulties, the Finish Line Judges will determine the order of finish.
  • Only Track Officials will be permitted in the track area.
  • Track Officials are responsible for the proper conduct of the races. Good sportsmanship and behavior are expected for all attendees. Race Officials may ask anyone not following this rule to leave.
