2005 Track Champion Felicia Martinez These Lightning Fast drivers show no hesitation or delicacy whatsoever when the green flag flies. They race under the same rules as the regular Factory Four 4 four-cylinder stock car division with only one exception: no guys allowed in this one.  Families often share the same cars for racing in the two different divisions. All Factory Fours alternate race laps on the large and small ovals, providing lots of thrills and chills for the spectators  when the cars crisscross at race speed in front of the grandstands.
