    2. Wheels & Axels
      1. Wheels and axels must be from the official pinewood derby car kit (BSA Part #17006) or from the new optional colored Cub Scout derby wheels & axle kit (BSA Parts # 17553,17554, 17555, 17556 and 17557). (Other wheels & kits, including “Razor” style wheels are available on the Internet that give an unfair advantage, and are prohibited)
      2. Wheel treads, axels, and hubs may be sanded or polished to remove burrs and manufacturing flaws.
      3. The tread width, wheel diameter, axel diameter, and hub diameter are not to be altered. Sanding a ridge or point on the tread or in the hub is not allowed.
      4. The following may not be used in conjunction with the wheels or axles: Washers, inserts, sleeves, bushings, springs, or bearings.
      5. Beveling, tapering, thin sanding, wafering, or lathe turning of the wheels is prohibited. (Lathing of wheels can make cars much faster).
      6. The decorative dots on the wheel treads may not be removed. The BSA logo on the inside of the tire must still remain visible in order to verify that it is from the official kit.
    3. Weights
      1. Any solid material may be used for weight (lead, tungsten, copper, steel, coins, etc.).
      2. Lead is permissible for weight provided that it is completely enclosed within the body of the car.
      3. Weights must be stationary and permanently attached to exterior or interior (by hollowing out) of car. Moving, sliding, or spring-loaded weights are not allowed.

      1. Only dry lubricant is permitted.
      2. Liquid/oil-based lubricant is strictly prohibited because it may leak out onto the track.
      3. Lubricant, if used, must be applied prior to registration of the car. No lubrication is permitted after registration or during the derby.
    5. Details
      1. Details such as steering wheel, driver, and decals are permissible as long as these details do not exceed the maximum length, width, and weight specifications.
