DAYTONA, FL (WWBT)
NASCAR announced today the base NASCAR Sprint Cup Series rules package to be used during the 2016 season. The package was delivered to teams after an extensive collaborative process between NASCAR and industry stakeholders.
The base package will include a 3.5-inch spoiler, a 0.25-inch front leading splitter edge and a 33-inch wide radiator pan. These components will provide lower downforce on the cars, and Goodyear will develop tires to complement them. Earlier this season, NASCAR Sprint Cup Series races at Kentucky Speedway and Darlington Raceway featured a similar aero package.
Characteristics of the lower downforce rules package includes more off-throttle time for drivers and decreasing corner speeds. This generates more passing zones over the entire track, and allows for multiple tire combinations to be levered.
In addition to the base package, each track will continue to feature specific rules, including tire combinations and drive train configurations, to create the best racing for each track length, layout and surface. Rear gear ratios will be adjusted to maintain a maximum engine speed of 9,000 RPM and a 1.38 third gear ratio will be used at all tracks smaller than 1.25 miles. The digital dashboard, which was optional for teams during the second half of this season, will be mandatory in all vehicles.
