Installing one of the front axles so that it lifts the wheel off the track is beneficial in several ways…

First of all, by only having three wheels on the track, the start-up inertia required to get the car moving is reduced by 25%… this is huge. 

Secondly, it simplifies the process of aligning your car since the raised wheel needs no adjustment.  Finally, if you’re going to create a Rail Rider, as we will soon discuss, you must raise one front wheel.

The best way to raise a front wheel is to simply drill one front axle hole higher than the others.  It doesn’t take much.  From 1/32 to 1/16” is plenty. 

Another way is to bend one of the front axles upward to lift that wheel off the track.
