It's a term race fans hear all of the time, so often that they hardly even think about what it means.
Sheet metal is just that - a flat sheet of metal.
Look at Winston Cup car, especially one going as fast as the cars will Sunday at Atlanta. The job of shaping that metal into the graceful, aerodynamically pure curves that make up a modern race car is done by people called fabricators. Tim Suggs and Greg Carpenter used to work as fabricators at Hendrick Motorsports. When the Hendrick operation agreed to help another team out with its bodywork, Suggs and Carpenter started doing that additional work on the side to earn extra money. N.C. Their company is called Body Dynamics Racing, and it is already enjoying success on the track.
