NASCAR confirmed today that it has finalized its aerodynamic specifications for Speedweeks 2014 at Daytona International Speedway.
The sanctioning body said that spoiler height for next month's Sprint Cup Series test, the 2014 Daytona 500 and all associated Speedweeks events for the Sprint Cup Series cars will be 4.5 inches; 1/2 inch taller than last year. That taller spoiler should provide more rear down force, helping to stabilize the cars.
NASCAR recently announced a new aero package for all tracks other than the superspeedways.
