Hello. First timer here. Helping my son with his pinewood derby car for cub scouts. Reading the Northen Star Council rules we are under, it says "2.3 wheelbase: the distance between the center of the front and rear wheel must be no less than 4 inches." It does not specify a maximium? Sounds like then extending the wheel base to as close to the ends as possible without having the wheels stick out past the end of the 7 inch block lengthwise is the way to go? Thanks.
