UPDATE: NASCAR Cup Series cars will have tweaks to the right-side passenger windows this weekend at Dover International Speedway in an effort to improve air flow inside the vehicles. The change comes in advance of a doubleheader weekend at a high-load track in Dover, a high-banked, 1-mile concrete oval.
A portion of the right-side window will be removed; details were spelled out in a memo to teams Wednesday. NASCAR officials will monitor the impact of the changes this weekend before deciding if the move is permanent.

ORIGINAL POST: Racer’s Kelly Crandall reports that NASCAR will allow teams to remove a good portion of the right side window on the cars to get more air flow in.
Several drivers complained about the heat in the cars last weekend at Daytona.
James Small said this morning NASCAR made a change to the right side window given so much talk of how heated drivers get. So, I checked. NASCAR has indeed sent a memo to teams for Dover. My understanding: to try to get more air in the car they’ve gotten rid of a lot of the window pic.twitter.com/JzIquTnlpS
