There are four crucial aspects of a classic car’s performance: straight-line top speed, cornering speed, acceleration, and braking. This book’s detailed guidance shows you how to improve each of these, whether for more enjoyable day-to-day use, or for a diverse range of classic motorsport.

This book explains what ‘high performance’ really is, analysing each part of the classic or retro car – the engine, transmission, brakes, etc – and showing how it can be modified and improved for greater performance, both with period correct parts (where available), and modern components such as electronic ignition. It provides specific guidance and planning advice, examining the pros & cons, and road or motorsport suitability of each modification. Whether you want a more practical, better performing classic for enjoyable everyday use, or a souped-up racer for a diverse range of classic motorsport, you’ll be able to make the correct choices using the tuning ‘menus’ and easy-to-understand troubleshooting tables. With a focus on both traditional tuning – such as overdrive units for gearboxes – and modern 5-speed gearbox replacements, as well as content on SU and Weber carburettors, this book will teach you how to modify a classic car for any purpose – without wasting money.
