NASCAR could implement step-splitter next season

Two components being considered for the Gen-7 car to debut in 2021 were utilized in this month’s All-Star Race at Charlotte Motor Speedway and one – the single-piece carbon fiber splitter/radiator pan – received such positive feedback that it could be adapted in the NASCAR Cup Series in 2020.

"I will say the feedback from the All-Star Race in particular with respect to the step-splitter has been very positive," John Probst, NASCAR’s senior vice president for innovation and racing development, told Motorsport.com on Wednesday. "In our next competition meeting with the teams we may elect to have the discussion with them if there is interest on their part that we may entertain adapting it in 2020."

"Actually, if we implement it correctly, it would probably cost-neutral to the teams, perhaps even a little cheaper in the fact the splitter and the radiator pan are incorporated into one piece," Probst said.
