    great book

    Posted by michael on 26th Jul 2016

    the book is great very thorough, covers just about everything that could be covered...... the book is not something you can just read once.... after you read it the first time it is so thorough you can't retain it all....... once you have read it once then you can go back and use sections separately when you are working on different sections....... great book will help anyone who races........

    Thorough coverage of Race Car Dynamics

    Posted by Unknown on 10th Oct 2014

    Excellent coverage of weight distribution and tire behavior. Good explanation of the equations in the software. The references to Milliken impressed me. I have some of his books too.
