The new height will be 4.5 inches which is up 0.5 inches from the 4 inches used in 2013.
The new spoiler height will be used first at Preseason Thunder testing for the Cup cars on January 9th and 10th. It will also be used during all of Speedweeks activity including the Sprint Unlimited and Daytona 500.
A taller spoiler should allow for more rear down force on the car which in theory should make the cars more stable. Could this also mean more tandem drafting than was seen with the Gen-6 car in its first season at the restrictor-plate tracks? A more stable car would seem to lend itself to that scenario.Tags: daytona 500, Motorsports, NASCAR, NASCAR Sprint Cup Series, Sprint Unlimited
