Participate in a Soap Box Car Derby Race
Register early to participate in a soap box derby race. As you get closer to race time, you'll find that available spots fill quickly, so it's better to sign up months in advance to guarantee yourself a spot.
Maintain your car in the weeks leading up to the race, and be sure to practice. Get your timing down, learn the balance of your car, and keep focused on increasing your speed as much as possible.
Test out new parts or materials that you wish to use in the soap box derby race. While you need to keep your car's parts within the race's specifications, there are no rules stating you can't upgrade parts to better ones when you can afford to.
Invite lots of people to join you at the race. The bigger the crowd, the more awareness you'll be able to generate for the sport. Believe it or not, this is one of the more important aspects of racing in a soap box derby. Ticket sales and attendance are what help keep the sport alive, so get everyone you know to come.
Be available for the judges when the time comes to inspect your car. Some races set up specific times to have your car inspected, so keep track of time and be there when you need to show any modifications you've made.
Bring the event's rules with you when you attend. Most events will have copies available, but having the rules on hand (as well as before the event itself) will help as you practice before it's time to go.
