Factory Stock racer Jay Dold is another NMRA participant turning over his program to MV Performance for decreased e.t.'s. Jay runs a Four-Valve in Factory Stock, and aside from wearing the Atlanta-legal slicks instead of the usual drag radials, the car was in Factory Stock-trim. We could tell, as an antiroll bar is illegal in Factory Stock. With the slicks on the car, Jay looked like Chubby Checker doing the twist on the launch. With antiroll-bar technology reaching most racers these days, it's weird to see a Mustang twist up. But Jay had the twist down and took the Olson Performance Factory Stock class at Atlanta race.
