The Lil' Green Book of Karting came about from my need to understand how to effectively set up a Kart chassis (either a rear brake only or front and rear brake shifter chassis). Being new to the sport, the need for understanding both these types of chassis led to extensive research. Information sources ranged from anecdotal information to academic papers that describe vehicle tire-grip performance under load. My background in physics and reliability maintenance helped me understand Kart performance theory, and I wanted to share this understanding with other Karters. For newcomers to Karting, the book introduces the important center of gravity (CG) concept to help them understand how things work. The need for this understanding was driven by the lack of consistent and consolidated information "out there." Newcomers to Karting don't have the language to form the questions they need to ask, and the book provides all the knowledge they'll need to understand how to make their Karts perform better. For young Kart drivers (and mechanics), the book develops Karting concepts in sufficient detail to help relate both driver and chassis analysis/setup to on-track performance if datalogger data analysis is available. With better understanding, young drivers can accelerate their skill development and experience better competition. Karting can be tremendously social for folks participating in the sport, and it can also be a pathway to a career in motorsports. Either way, knowledge helps make the experience more enjoyable instead of struggling with understanding and discouraging results. Happy Karting!
