NASCAR allowing teams to remove a portion of right side windows at Dover

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.
