Following a test, the superspeedway NASCAR package has been adjusted
NASCAR has issued a few changes to the superspeedway rules package for 2019. The changes will take action in the Monster Energy NASCAR Cup Series division.
The Daytona 500 was won by Denny Hamlin back in February. Yet, the 2019 rules package has yet to be showcased on superspeedways. The 2019 Daytona 500 was completed using the 2018 rules package which also included a restrictor plate.
Following that race, NASCAR hosted a test session at the 2.5-mile track with the upcoming 2019 rules package. Despite the increase in downforce, the speeds were higher than expected.
The results from that test have created an amendment in the rules for 2019:
–The rear spoiler will be increased from 8″ to 9″.
–1″ bolt added to track bar mount. This changes the height to 12″
New for the 2019 superspeedway package: A standard radiator pan, aero ducts, 9″ spoiler (1″ higher than standard 2019 package) and aero ducts.
In superspeedway races going forward, engines will be fitted with the tapered spacer. The upcoming race will be the first superspeedway NASCAR event run without a restrictor plate since 1987.
The next superspeedway event for the Monster Energy NASCAR Cup Series takes place at Talladega Superspeedway in Alabama on April 28th.
