Chassis Engineering (the art of), is not something to
take lightly. The design, modification, and construction of an
automotive performance chassis is perhaps the most complex
undertaking an enthusiast can attempt.
Many of us want the ultimate in performance from our
vehicles chassis and suspension. Whether it's crawling the rocks of
the Rubicon, or skipping the whoops of Baja, stock components
rarely cut the mustard, and so the quest for more performance
begins. Before breaking out the torches and MIG however, there are
a few things you should know.
"Chassis Engineering" (the book), by engineer turned
motorjournalist Herb Adams, is a good first step on that path to
knowledge. Adams goes into a decent amount of detail, familiarizing
the reader with the relevant terminology, materials and tools
involved, and most importantly, the theory behind "why" things work
the way they do.
What is "instant center" and why
should you care? What role will center of gravity play in designing
a new foundation for your vehicle? Are there benefits of IRS over
Live axle? These are but a few of the issues dealt with in "Chassis
Engineering".Within a few pages, the
reader comes to the realization that extensive and expensive damage
could occur easily, and/or greatly decreased performance to their
vehicle if they just start "hackin and weldin."Every modification you make will effect all other parts of the
vehicle. Knowing which mods to make, what material to use, and how
to make it all work together is the key to successful chassis
work.

The Verdict - 4
While "Chassis Design" is not written specifically
for 4x4's, the principles still apply. Adams has written a very
good and easy to understand reference work that builds a solid base
of knowledge for the neophyte chassis wizard to expand upon. While
this book isn't "light reading", it is "essential" reading for
anyone short of a professional fabricator who intends to make major
mods to the chassis and suspension of their vehicle. With the
increase of "custom" suspensions coming out of off-roader's garages
today, this book could be just what the doctor ordered!
