NASCAR News: Air deflector on right side of car mandated

NASCAR will mandate a new right side rear-window air deflector beginning with Saturday’s Coke Zero Sugar 400 at Daytona International Speedway.

Following wind-tunnel testing this week, the added component to the Next Gen car increases the liftoff speed of the car in the early part of the spin, making it less likely it get airborne.

The mandate comes in response to Corey LaJoie’s flip at Michigan International Speedway after the No. 7 Spire Motorsports Chevrolet went in the air and landed on its roof shortly after spinning down the backstretch.

NASCAR will supply teams with the part, and it will match what is currently run on the left side rear window.
