How to Set Your Pinewood Derby Axles to the Neutral Position
First, Install the rear wheels with the 2.5-3.0 degree axle. (negative camber)
Next, use the Pinewood Derby Axle Extraction Pliers to turn the axle until the black line is in the 12 o’clock position.
Checking Your Adjustment
To see if you are close to the neutral position, hold your car up against a white background.
The wheel should be parallel to the body of the car.
If your adjustment is off, turn the wheel accordingly until it matches the parallel position.
Common reasons for being off:
You did not mark your line straight on the axle head. (most common)
Your axle hole or slot is not drilled properly (improper angle, depth, etc)
