Changes from 2016 to 2017
"The rear spoiler will be smaller, reduced one inch to a 2.5-inch height. The splitter will also be shortened from five to two inches wide and the length is reduced from 61 inches to 53 inches.The combination of the splitter reduction and the spoiler reduction will drop the downforce to 1,500 pounds."

Changes from 2017 to 2018
"Chief among the handful of changes on the aerodynamic and technical front are the use of a common flat splitter and radiator/oil cooler for 2018.
The radiator/oil cooler move is something that is already in play at superspeedways. The common splitter, meanwhile, will be new for all venues.
“As we do that, some of the downforce will be removed from the car, so we will see a rearward shift in the balance of the car,” he said. “We estimate somewhere between two to two-and-a-half percentage points backward (approximately 100-120 pounds of downforce)."
