Clint Bowyer’s spotter said on a podcast this week that NASCAR will use restrictor plates for next month’s All-Star Race at Charlotte Motor Speedway. It would be the first time restrictor plates have been used at that track in Cup.
“This is going to happen,’’ said Brett Griffin on the podcast “Door Bumper Clear on Dale Earnhardt Jr.’s Dirty Mo Radio. “They’re going to put restrictor plates on these cars for the All-Star Race. They’re going to knock like 250 horsepower off. We’re going to run, I think we’re basically running the Xfinity package from Indy … last year. I was told top speed is going to be around 170 miles an hour.’’
NASCAR would not confirm the change Tuesday. NBC Sports has learned through industry sources that are not authorized to speak publicly about it that the move is expected to be made. Teams are expected to be notified soon and an official is scheduled for 6 p.m. ET Wednesday.
“We have had several discussions with the industry on the format of the Monster Energy All-Star Race, and will have an announcement soon,’’ NASCAR’s statement to NBC Sports read. “The fan-favorite event will again showcase the sport’s top talents in a unique way, and as always, we’ll ensure that the format will offer the best race for our fans.’’
NASCAR has continually altered the rules for the All-Star Race. In some cases rules for the All-Star Race have gone on to be used in points races, including double-file restarts with the lead-lap cars at the front and stage racing.
The All-Star Race is scheduled to be held May 19.
For last year’s Xfinity race at Indianapolis, NASCAR mandated:
A 7/8-inch restrictor plate
Taller rear spoiler
That same package will be used in the Xfinity Series this year at Indianapolis, Michigan and Pocono.
