Veloce Publishing has issued a number of books in their SpeedPro Series that illustrates practical automotive performance tips and advice. This softcover book conations 96 pages of honest and engaging information on “How to Build a Successful Low-Cost Rally Car.”
It is first and foremost a primer that shows you how to enter the field of long-distance endurance racing on a budget but it also has information and close-up photos of the kinds of modifications that can be used to recreate an authentic replica of those spartan race cars in scale.
The book is British-centric and many of the automotive terms like bonnet and windscreen (just as the races are) are prevalent but are easily understood from context so it’s still a pretty easy read.
