Following a month of safety incidents that included a blow-over incident involving Joey Logano at Talladega Superspeedway earlier this year in April and visibility issues at Circuit of the Americas, both in the NASCAR Cup Series,, NASCAR announced June 8 it will implement new safety precautions to its road course and superspeedway packages.
For the tapered-spacer events at Daytona International Speedway and Talladega, cars will use reduced hole spaces from 57/64″ to 53/64″, which is a reduction of approximately 50 horsepower.
Additionally, the wicker on the spoiler has been removed, an additional roof bar will be mandatory at superspeedways.
For road courses, two flashing lights will be mandatory on the rear end of both Xfinity and Cup series vehicles.
The next races these rules will be implemented at is the July 4 Cup and Xfinity events at Road America.
