I won first place in the pinewood derby one year when I was a kid. All the technology is in the axles and wheels and getting the weight right. I don't know how it is now, but back then they had a max weight for the car, and my dad drilled holes into the bottom of the body and melted lead into the holes to get the weight just right. Now, they'd probably throw you in jail and take your kids away for having lead any where near your kid...
Maybe that's why I turned out a little :nuts:
