Much of NASCAR's insider culture revolves around the garages of the various racing teams. Between races and between seasons, mechanics and drivers are constantly tinkering with their cars to tease out every bit of extra speed. The racing teams and NASCAR inspectors play out a constant tug-of-war, the latter making sure no car has an unfair advantage at race time. This book also explores the physical makeup of the cars' materials, as well as the business end of owning a race team.
