Setting your wheel gaps to the proper amount is crucial!  Too much gap and the wheels will move back and forth on the axles, causing the car to wiggle and lose speed.  Too little space and the wheel will bind against the body.  For the perfect gap, place the tool between the car body and the wheel's inner hub, and push the wheel/axle into the body until tight.  It's that easy!
