Buy this last...
...after you've bought ALL the other Carroll Smith books. They're all 5 Stars, this one is just a more detailed analysis of what's covered in his other books. This was exactly the book I needed to take on a major race car project. I read this book, and then re-read Tune to Win, as I then had a better understanding of the science and theory behind the principles presented. This is not dry stuff, and is very accessible to mere mortals such as myself. Funny, smart, and very sensible.
