My son (cub scouts) just finished a similar competition. 5oz max. The key was to have the kids do most of the work. Parents helped making the basic shape, i.e., jig saw, and then the boys do most everything else on their own. Sanding, painting, etc.
After he was done, our goal (for speed) was to get back up to the 5oz target. I drilled holes underneath the car and put lead weights in the body. When dealing with a gravity competition, being up to the weight limit is important.
Other than that, making sure that the wheels were level and straight with each other was important. If the car drawed to one side or the other, speed would be greatly affected by the "rub" on the track walls. Powdered graphite on the hubs/nails decrease the friction dramatically!
The boys who had participated in prior years did much better than the 1st year kids. Also, (not fair!) the cars that were obviously constructed with too much parental supervision (or total) had a distinct advantage in winning, but not in pride.
