The Derby Evolution Air Guides are designed to improve the times your Pinewood Derby car is running, typical improvements of .005-.007 in times. Air flow into the wheels causes turbulence and will slow your car. These Air Guides are designed to stop that flow of air into the wheel and direct it around the rear of the wheel. Today aerodynamics play a vital roll in a winning Pinewood Derby car. These are designed to give you an advantage over your competition.
These are very easy to install and use. They attach to the body with glue. Using a old wheel and axle, apply a small amount of glue to the back of the Air Guide, install the axle into your axle hole or slot. Push the axle and wheel all the way in. The axle and wheel will center the Air Guide. Allow the glue to dry and remove the axle and wheel, the Air Guide will be installed. The Air Guide is designed with clearence for the center rail of the track, this area is to be pointed down when installing the air guide.
