Pack 116 follows the same guidelines as the Wright Brothers District.
**Cars must be built with the BSA Official Grand Prix kit handed out by the pack. **
Here are the District Spec’s:
A. The car must have been made during the current year (the year in which the derby is held).
B. Width - overall width shall not exceed 2.75” (2-3/4 inches).
C. Length - overall length shall not exceed 7 inches. (Note: check your length, cars out of the box are sometimes over 7 inches.)
D. Height - overall height shall not exceed 3.5 (3-1/2) inches. (Note: the starting gate on the track is the reason for this limit. You can exceed this limit for judging, if the item can be removed when racing.)
E. Weight - Shall not exceed 5 ounces.
F. Wheel bearings, washers, bushings or hubcaps are prohibited.
G. No solid axles, only the official Grand Prix Pinewood Derby kits with nails for axles can be used. Wheel base can not exceed 4.75” (4-3/4 inches) Center to Center of axle.
H. The car shall not ride on any kind of springs.
I. Dry Lubricant only. No Liquid Lubricant allowed. [For more info, look for Hob-E-Lube or Tube-O-Lube graphite lubricant at your local hobby store or favorite on-line merchant]
J. Wheels can be sanded to remove surface imperfections, but the treads must be left flat. Wheels can not be any smaller than 1.170” diameter. Can not remove any significant amount of plastic - inside or outside of wheel. Only the official wheels supplied with the Grand Prix kit are acceptable. Car with modified wheels will be disqualified to run. No hubcaps of any sort are allowed.
K. Must have a .375” (3/8 inch) clearance under the car body. Low hanging weights must be moved to an other part of the car or recess into the bottom of the car to pass the .375” clearance.
L. Any details added must be within length, width, and weight limits.
M. No loose materials of any kind are allowed on the car. If anything falls off during or after a race, it stays off.
In addition to the district rules there are a few important specifications required for racing on the pack track:
Minimum Width Between wheels on both the front and the back is 1 and ¾ inches due to the design of the pack track.
No part of the car shall be allowed to extend past the starting gate. Keep in mind the starting gate uses a single ¼ inch vertical pin that sticks up 1 and ½ inches above the track. This should be kept in mind when designing the front end of your car.
As stated earlier all parts must be standard BSA parts from the Grand Prix Pinewood Derby kit. NO special wheels or axels are PERMITTED.
The decisions made by the race committee to resolve any conflict will be final. Membership on the race committee is open to all those that are interested.
