NASCAR firms up technical rule changes for 2014 Sprint Cup season

Charlotte NASCAR test December 2013

NASCAR has issued its 2014 rules package to Sprint Cup teams following a collaborative development process.

The series has settled on final specifications for the upcoming season after gathering input from across the industry, including the recent 30-car test at Charlotte.

Changes include statically setting the cars' ride height and eliminating the pre- and post-race front height regulations and inspections.

The rule package also provides for a square leading edge on the splitter, side skirt and rear fascia tweaks, and an eight-inch rear spoiler.

The modifications are completed with the addition of a 43-inch by 13-inch radiator pan.

"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.

"We looked at a number of important factors when finalising what the 2014 version of the race package will look like.

"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 new package will not apply to restrictor plate races, including the season-opening Daytona 500 in February. It will be deployed for the first time at Phoenix on March 2.
