NASCAR makes even more changes to damaged vehicle policy after Bristol

NASCAR made some changes to its Cup damaged vehicle policy following the race at Bristol Motor Speedway. Teams can now replace the diffuser flaps while preparing a vehicle.

“NASCAR updated its Cup DVP policy where it used to not allow teams to replace the diffuser flaps but now they can replace the diffuser flaps (extensions) when making their repairs,” Bob Pockrass of FOX Sports wrote on X/Twitter. The diffuser flaps help keep the car on the gound.
