The people running the pine wood derby are free to adopt any rules they want too. There are no BSA mandated rules. If your council or district is running a pinewood derby, it will be run under rules they have adopted, and if you planning to go on to that, it is smart to use the same rules. In any case, if I bought a car kit at the local scout shop, and told after the fact it was not legal, there would be an unpleasant committee meeting that week. So make your pine wood derby rules clear in the very beginning & remember it is about having fun.
Also BSA is now licensing kit sold in places other than scout stores. Are you really going to tell some one they cannot use an "Officially Licenced BSA Pinewood Derby Kit"
