What Does It All Mean To Me?
Chassis information can help you better understand what you are seeing on the race track. For example, lets say you hear over the scanner that your favorite driver's car is really loose on cold tires but gets better over the long run. This will explain why he's just trying to stay out of the way on the restart. But you can look forward to him making a charge later in the run.
Being more aware of what's going on during the race will make you more involved in the race, more knowledgeable about NASCAR and you will have more fun at the races.
The Conclusion
There is no doubt that having a scanner adds a great deal to the experience of attending a race. It allows you to better understand what is going on with individual teams and gives you a better sense of what issues are affecting the race. For example if the teams are worried about tire wear or if the teams think that weather may be a factor you will know it.
The scanner provides inside information to help you better appreciate and understand the race in front of you.
