A local grocery store could furnish refreshments such as cold drinks, chips, and maybe even hamburgers and bread for track consumption. This gives them a tie-in to the community and shows it supports the local race team by having its name on the car. The local auto parts store might offer up a set of ball joints or other relatively cheap parts that would keep you racing and lower your budget.
Conclusion
The point we are trying to make here is that in order to be successful, you need to be organized. The more organized your team is, the more successful you will be. I don't know any teams that win on a consistent basis that are disorganized.
Team meetings should take place in the pre-season, during the season many times, and post season. I once consulted with a team who regularly met around a conference table. When I was back home in Florida, they would call me from the shop in Wisconsin on a conference phone with all of them seated around a table. They won a major NASCAR series championship that year. Let's have a meeting.

In the busy and loud environment...

In the busy and loud environment of the racetrack, we need to be able to communicate. When all crew members have on headsets, then the crew chief can make sure things get done quickly. If you can afford a radio system, then by all means get one. It will help eliminate a lot of confusion and frustration.

Things can get busy around...

Things can get busy around the car on race day. This team works well together completing each task while not interfering with others' tasks.

When we talk about communication,...

When we talk about communication, we need to include the track officials. How well did your team get along with the track personnel? Could your relationship be better? You don't have to love the officials. You just have to get along reasonably well. If your team is a winning team, the officials might look more closely at what you are doing and that might not agree with the team. Look at it as flattery. Losing teams get no attention at all.
