From Pathfinder Wiki
If the bottom of a pinecar contacts the track, it will exert a tremendous amount of drag on the car. It might not even make it down the track if this happens. The most common way that a car will come into contact with the track is if weights are added to the underside of the car without countersinking them. Always countersink your weights so that you know the car will not drag on the track.
