The device was introduced for the 2015 Cup season so that drivers could influence the handling during the changing conditions of a race.
NASCAR claims drivers had approached the series over a desire to lose the driver-adjustable track bar.
“We’ve had the driver-adjustable trackbar for quite a while now and many of them [the drivers] came to us and said, ‘Hey, look. This really didn’t do what we’d hoped for and we’d rather not have it,’” Scott Miller, NASCAR’s senior vice president of competition, told SiriusXM Radio.
