NASCAR is reducing the size of restrictor plates used at Daytona in the Sprint Cup Series, to hopefully make racing safer for the drivers. NASCAR Sprint Cup Series director John Darby said that by reducing the size of the restrictor plates, the amount of horsepower will decrease, and a some of the top-end speed will be taken away from the cars.

The fence at Talladega will be raised from 14 feet to 22 feet after Carl Edwards' last lap crash into the wall in the spring race. Seven fans were injured from debris that flew from Edwards' car, one of which was a teen girl who suffered a broken jaw.

The fence at Talladega will be raised before the next race, which is Nov. 1. The fence at Daytona will be raised before it's first event in January.
