NASCAR has implemented a new rule effective for the four superspeedway races at Daytona and Talladega this season requiring the total rear weight of the right rear and the left rear to not exceed 50-percent of a car's minimum weight.
For example, a car required to weigh 3400 pounds must not weigh more than 1700 pounds across the rear wheels.
Winston Cup series director John Darby said Tuesday the rule was adapted to prevent teams from circumventing the rear shock and spring requirements at Daytona and Talladega.
"Teams were starting to add more and more weight to the rear of the cars, which was sitting on a specified spring," he said.
"Part of the direction teams were using to beginning to head in was actually changing some of the tubing sizes which could affect the crushability of the rear of the car."
Darby said NASCAR did not want to allow teams to chance compromising the safety advantage in rear crushability.
