7 simple steps that ACTUALLY MATTER to building a winning pinewood derby car. I built a car in 45 minutes using these steps and crushed all the competition by more than 2 car lengths (proof is in the video :) Special thanks to Steve at DerbyMonkey.com for providing his expertise and materials for the video.
