Pickup points are important, but what the chassis does between those points is just as important. I've witnessed one late model team struggle early in the year cut out one bar with a sawzall and their whole season turned around. One of the top modified builders is known to sleeve some key areas of the car to allow it to flex and it can be seen by the powdercoat being wore off in the area where it moves. There is definitely a science to chassis building that not every builder understands.
