Book Description: The iconic Porsche 911 is that rarity--a world-class performance car that can still be improved. This book shows anyone with the tools and a modicum of skill how to make this great car even better with performance-enhancing tricks and techniques ranging from subtle to extreme. Focusing solely on the air-cooled cars produced from 1963 through early 1998, this third edition of the Porsche 911 Performance Handbook provides clearly illustrated, easy to follow instructions for making modifications to every working part of the car, from engine and transmission to suspension, brakes, wheels and tires, and more. Author and noted Porsche expert Bruce Anderson goes into questions about buying a 911, custom treatments, and maintenance. Detailed appendices list tune-up specs, conversion charts and handy formulas, and resources.
