Testimonials:

"I have read this book probably 10 times. Each time I read it I learn something new. When I get upside down in my 4-link suspension, I pull out this book and go back to basics. It is written so that any high school graduate can understand it but a lot of the material and concepts are college level. If you want to understand how your race suspension really works, I highly recommend this book."

"Great Book!!! I have read this book over and over and learn something new each time. I have assisted in the construction of full tube chassis prior to this book and learned a good deal about what is written in this book. After reading the book, I have a true understanding of why we built things the way we did. There is a ton of information that most drag racers do not know in this book. After reading Door Slammers, you will find out how ignorant most people are when it comes to chassis setup and how to make a car hook. You'll see that what you used to do in order to hook, is probably wrong. You will also find out what you should have done. This book is a must have for all drag racers.

AUTHOR BIO:

Dave Morgan owned some extensive motorsports credentials before joining the drag racing industry.

In college, he started auto-crossing sports cars then began his wheel to wheel racing experience in go-karts, eventually graduating to formula Fords in the mid-seventies. After working for a while as General Manager of ARE, a dry sump manufacturer in Sacramento. Morgan started his own traveling seminar company, Morgan Motorsports Network.

Northern California TV viewers may recognize Morgans familiar face since it was at this time when he also worked with KXTV in Sacramento as their motorsports reporter and had his own auto-shop series on PM Magazine.

Aiston Industries introduced Dave to the world of drag racing when he was hired to organize their sales program and start the successful 'Tech Tour' that made chassis seminars so popular in the early eighties. In 1982 he was chosen as a 'Hi Riser' by Car Craft Magazine. After three national seminar tours, Morgan moved to Baltimore to work for ATI Transmissions where he complimented his chassis tuning experience with knowledge about torque and its relationship to suspension work.

The desire to return to the chassis industry was rekindled when he was offered a position at Zeeker Performance in Hicksville, Ohio. As the General Manager there, Morgan sponsored drag racings first ever

chassis pad at Norwalk Race Park and also began his early career as a writer by supplying tech stories for National Dragster, Drag Review, Super Stock and United Racer.

These days, Morgan makes his living as a free-lance writer and lives on his horse ranch in West Virginia where the states central location makes it easy for him to reach east coast and mid-west race tracks.
