When you sign a contract to race with another team, you will have two options: create your own car and join that team as a new teammate or replace a driver on that team. For example, if you sign a contract to race with Hendrick Motorsports, you can create your own custom car and race with the #48, #9, #24, and #88, or you can choose to hop in one of their existing cars. New to NASCAR Heat 4, your name will appear on the back of your car, cementing your status as a real NASCAR driver!
