In Drivetrain battles you will go up against cars that have the same drivetrain you have chosen to go up against. You can only race cars that are the same drivetrain as the event you are choosing to do. example, you cant go up against a AWD event car with a FR, but you can do the RR event with a RR car This is the only way you can get Rims outside of events.
