Ultimate Rail Rider Kit

The Derby Monkey Ultimate Rail Rider™ Kit gives you everything you need to build a Rail Riding Pinewood Derby car.

Experts agree: Professional Pinewood Derby car builders agree that controlled rail riding will produce a much faster car.  Yes, that’s right; if your car consistently rubs against the rail all the way down the track it will be faster.

Here’s why: It is nearly impossible to have a track that will allow a perfectly aligned car to run straight and not hit the rail. Invariably, any car will drift into the rail causing it to bounce back toward the other side.  This generates a side to side movement, causing the car to repeatedly slam into the rail.  This is actually the number 1 enemy of a speedster. Therefore, knowing that you will certainly be hitting the rail (evidenced by almost every video of a fast car that you study in slow motion) you should bias the car to gently ride the rail on the front dominant wheel side.

Building a Rail Rider is easier than you think:  This kit will systematically step you through the process one simple step at a time. The kit includes the detailed handbook “How to Build a Rail Rider™” that clearly explains and diagrams the details of preparing and aligning your car to ride the rail and blow the doors off the competition.
