The Derby Worx Facts!
• Derby Worx has exclusive tooling custom made under contract for Derby Worx.
• Derby Worx builds all of their custom fixturing in house.
• Derby Worx nor Derby Monkey charge extra for the coning or hub work like many of our competitors.
• Derby Worx only uses BSA Pinewood Derby wheels made in the USA. This means better quality!
• Derby Worx sorts every batch of wheels and hand selects the best wheels from the best molds (mold matched). Over 25% of the wheels are scrapped in favor of only the absolute very best wheels. This means better quality wheels for you!
• Derby Worx wheels are RACE READY right out of the package!
Note: Lighter wheels are only one of many factors that make a fast car. Light wheels alone may not improve your speeds. In addition to light wheels you must also have adequate lubrication, alignment and weight placement.
Not all BSA pack rules permit these Inertia-Lite wheels. Please check your local rules to see what wheels are permitted.
