Changes coming to NASCAR roll cages in 2013
NASCAR has issued technical bulletins in both the Sprint Cup and Nationwide series that address a safety enhancement to the driver's roll cage and will take effect beginning in January 2013.
The cars in both series will feature an additional forward roof bar and a center roof support bar that will intersect near the front center of the roll cage. This addition comes following extensive testing at the NASCAR Research & Development Center and is an effort to strengthen the roll cage and help make it an even safer compartment for the driver.
