Not to oversimplify it, but there are two adjustments on the East/West clutch. The base adjustment applies the clutch to get the car moving off the line or in the pits. It is made by turning a series of set screws that adds pounds of pressure per turn. The counter adjustment applies pressure above a certain rpm. Counter adds to base and is adjusted by adding or subtracting weight to the spinning mass using weighted nuts and bolts. If there is too much counter, the tires spin; if there is too little, the clutch burns. The two adjustments combine to make a magic combo that Jud didn't hit on the first run.
