Following multiple drivers complaining about the turtles at Charlotte Roval, NASCAR has decided to make a change by replacing the turtles on turn 16.
The turtles in the frontstretch chicane were replaced by NASCAR with 2.25-inch humps. They had previously been four inches high. NASCAR also released a bulletin on the decision to adjust the turtles.
“Following feedback from drivers and a review of data, NASCAR and Speedway Motorsports replaced the blue rumble strips on turn 16,” the bulletin read . “Last night, the blue rumble strips (4 inches) were replaced with red and white strips (2.25 inches). The new strips were painted blue, and the rules will not change.”
Since the change has been made, crews and drivers have been observed looking at the changes to the course ahead of the race. That included Michael McDowell and crew chief Travis Peterson who measured how far the car can go over the new turtles.
