Tricia Day is JJ’s wife and one of the Memphis family’s strongest racers when she sits behind the steering wheel of her famous ’66 Chevy Nova called Heifer. Like the other women in the Memphis family, Tricia is very comfortable working on her car to get it ready for races, and at just around five feet tall, Tricia may not seem like much of a threat, but don’t bet against her on a street race because you’ll likely go home with empty pockets.
