Erica asked us (including the TV side) to drop the Stevens on her last name. It was causing confusion for her. As silly as it sounds to us insiders, many who don't follow the sport didn't realize that she was the same person who Disney made the movie about. Her entire history in NHRA has been with the name Enders and she will use that professionally going forward.
She and Richie just built a new house and are still going strong, this is simply a move to simplify her identity to those outside of the sport.
