The Extreme Gravity Racing Series looked like a big-time motor racing event without the motors. Drivers, who trained for months, each came with a pit crew of nine. Their carbon fiber-and-aluminum racers cost $20,000 to $100,000 to build, organizers said. The 29 teams from throughout the state were sponsored by automotive companies and others.
