Drivers either own their car or might drive someone else’s car. Each driver needs a pit crew (usually 2-6 people) to help them set up the car for the current track conditions. Setting up the car involves making adjustments to tires and suspension parts to get the best performance out of their car. Learning how to property set up a race car can take years of practice to get right.
Each driver receives a payout (purse) for putting on a show for the fans. The amount varies based on car class and where they finish in the race. CLICK HERE to view the purse for each car class.
The weekly payout a driver receives will never cover their weekly cost of racing or the overall investment of their race car. Drivers are always seeking business or individual sponsors to help fund their race team in exchange for publicity in the locations in which they race.
If you are interested in sponsoring a driver or race team, you can find out more information about them by contacting them, or by buying a pit pass and talking to drivers on race night.
We suggest learning about a driver/race team before sponsoring to make sure their values, believes and action on and off the track align with yours. Some drivers are out in the community volunteering with kids programs, using their race car to help raise awareness/money for a cause and others just want to race. Each driver needs funds to support their race team and some will align better with your business/personal goals more than others.
