Changes to the package include statically setting the race car ride height and eliminating the pre- and post-race front height rules and inspections. Several teams were penalized for ride heights in both pre-race and post-race inspections.
“It was important to get the final pieces of the rules package to teams as quickly as possible following the final tests last week,” said Gene Stefanyshyn, NASCAR vice president of innovation and racing development. “Throughout the process, we gained valuable data that informed many of the changes for 2014. This data will prove useful as we continue to evolve the racing product into the future.”
The 2014 package includes a square leading edge on the splitter, side skirt and rear fascia adjustments and an eight-inch rear spoiler. Finally, a 43-inch by 13-inch radiator pan will round out changes for 2014.
“We looked at a number of important factors when finalizing what the 2014 version of the race package will look like,” Stefanyshyn said. “The Gen-6 car has been a great asset to our sport. As we continue to improve and develop the racing product, we’ll rely significantly on the critical data that has been generated by the entire industry over the last several weeks. We’re extremely appreciative of those efforts.”
The first race featuring the new package will be at Phoenix International Raceway on March 2. NASCAR said the package would not be used for restrictor-plate races, including the 2014 Daytona 500 on Feb. 23.
