Well-designed suspension systems not only keep a car's wheels in firm contact with the road for better control during hard braking and high-speed cornering, but they also increase the efficient transfer of the engine's power. Indeed, despite power lost to emission controls, the lap times of a modern Showroom Stock Class racer are often quicker than those achieved by a more powerful Production Class sports car of just a few years back. Colin Campbell has accomplished something unique and praiseworthy in this book; he has made it interesting, readable, and useful for the auto enthusiast-without omitting the mathematics that are needed by an engineer. There are many detailed diagrams and illustrations to make arcane concepts accessible. This book belongs in every car designer and enthusiast's library.
Colin Campbell held various senior engineering positions, both in Great Britain and the US, and was Senior Development Engineer with I.C.I. Ltd. From 1955-59 he was Managing Director of the Sports Car Garage, Blackburn, Lancashire, specializing in the maintenance and tuning of sports cars; and after this, Senior Project Engineer with the Walker Manufacturing Co. in Wisconsin. His interest in racing sports cars has included not only their design and maintenance, but also their performance, as shown by several years participation in Club racing.
