2018 SprintX GT Championship Series explained

The 2018 SprintX GT Championship Series is the final season of the SprintX GT Championship Series. Michael Cooper and Jordan Taylor are the defending champions in the highest class, the Pro class in GT. It is the second season sanctioned by the United States Auto Club. The season began on 23 March at Circuit of the Americas and will end on 12 August at Utah Motorsports Campus. GTS cars are separated from GT and GT Cup, as the GT4-based category has its own races this season.^[1]
