DMSBD Tech Tips

The Purpose of Tech Tips
 Like most racers we purchased a car, built it to the somewhat confusing directions, raced, and got soundly thrashed by the competition. Then we talked to experienced racers who helped us understand how to improve our car’s performance and how our driver could go even faster by using good driving strategy.

Eventually we got better as we learned more about the cars and how to adjust them for improved performance and as our driver became more skillful. We thought it would be useful to collect the many tips we received from our fellow racers into some neatly-written articles.

Then, by sharing these car building, setup, driving, and strategy tips, we hoped to help other newcomers to this sport build their cars correctly from the start and get up to speed quicker and easier than we did. We further believed that these articles should be freely available to all racers wherever they are. That’s how Tech Tips came about.

Disclaimer
As the rule changes continue to accumulate some of our older articles become partly obsolete. For example, those nice pictures and the description of center drilling kingpin heads in Construction Article 3. Drilling kingpin heads for setup was prohibited starting in 2005. Now they can only be prick punched. For practical purposes it’s just as accurate. It is strongly suggested that before following any of our tech tips, you read through and fully understand the rules for the current race season. They can be obtained here: AASBD RULE BOOK

Tech Tips By Category
Many of the tips we post come directly from the DMSBD Kids themselves as well as other derby sources. Here at the DMSBD Kids web site, we encourage our kids to take an active part in the site. Any and all tech tips submissions are welcome however, no matter where you are from. Submit tech tips here!  More categories will be added as needed.

Plans For Building A Derby Racer
One of the most frequently asked questions asked on DMSBD Tech Talk and in our Guestbook is: "Where can I find Plans for building a Soap Box Derby Racer?" Currently, nearly everyone racing in the two main sanctioning organizations, AASBD and NDR, uses the kit cars from Akron. The plans may be ordered from the AASBD or you may download and print them at no charge.
