I have been making pinewood derby cars for a LONG time. Using trial and error and published physics backed research, I have come up with the proven formula that yields the fastest and most consistent results. I am fortunate to have the space and resources to build test cars on my 42ft remote activated 4 space sensor test track. After thousands of pinewood derby builds, the cars just get better. I have tested countless Pinewood Derby products and cars from various vendors and I know what works and what is the best. I am pleased to share this with you!
