Alphonso Peluso AKA 'The Fonze' has been racing in the leagues since 2016. He was bitten by the pinewood derby bug after he and his son entered their first scout pinewood derby race. Alphonso is an Architect and College Professor who's work is centered around 3D Printing. All of his derby cars are 3D Printed and he was the first racer to build 3D Printed Cars. He spent 2 years perfecting his 3D Printed Car Bodies. In 2018 he became the first racer to win the Man of the Mountain with a 3D Printed Car when he won the Unlimted Championship. You can now purchase the same car bodies that Alphonso has perfected over the years.
