RULES PACKAGE
Teams will use the 2019 rules package with new tweaks specifically tailored for superspeedway racing at Daytona — the first time used at the track following restrictor plate usage at the Daytona 500. The package includes a 0.922-inch tapered spacer (replacing the restrictor plate), 9-inch rear spoiler, 1-inch bolt-on track bar mount, a tapered radiator pan, two-inch splitter overhang and aero ducts. Just as at Talladega in April, teams will use a 1-inch wicker extension placed on top of the 9-inch spoiler.
Cup Series teams also will participate with a new left-side tire compound for the Goodyear Eagle superspeedway radial, a construction update that makes its debut this weekend. The update was recommended after a two-day test at Daytona in February. Teams will be provided with two sets of tires for practice, one set for qualifying and seven sets for Saturday’s race — six race sets plus one set transferred from qualifying or practice.
“The goal was to incorporate the basic elements of the 2019 rules package into the aerodynamic configuration for the superspeedways of Daytona and Talladega, so they are no longer unique in that perspective,” said Greg Stucker, Goodyear’s director of racing. “With that alignment established early in the test, we took the same approach to the tires. The result was a tire combination with the same constructions we run at the intermediate tracks, married with the tread compounds run at Daytona in February.”
