I found GOING FASTER to be a very useful textbook. The organization is excellent, allowing me to skip some basic information and go directly to the areas which concerned me the most. The clear an detailed description of exactly how a racing car is driven through corners helped me analize my own driving and improve my performance.
The description of each aspect of racing starts with a technical foundation and then builds to a description of how to do it in the car. I am an engineer by traning, so this combination of a theroetical treatment with practiacl advice is excellent for me.
I found the descrption of how things are in racing to be right on, and I would recommend this book to anyone who would like to try racing, as well as to the racer who wants to improve his or her perforamnce.
