Charlotte Motor Speedway will condition the upper groove of all four turns ahead of this weekend’s action.

The goal is to add Goodyear rubber to the surface and widen the racing groove. The track will use both a tire dragging as well as lay down VHT, or resin, which was used earlier this year at Bristol Motor Speedway.

“We talked through this opportunity with the track, teams, drivers and Goodyear,” NASCAR senior vice president of competition Scott Miller said. “There was agreement that this process would enhance the racing we see at Charlotte Motor Speedway and ultimately would make for an exciting Coca-Cola 600.”

In addition to the Coca-Cola 600, the Xfinity Series will also be in action at Charlotte on Saturday afternoon.

Last weekend, the All-Star Race drew negative reviews for the lack of action. Following just three passes for the lead in the 70-lap event, Ryan Blaney said post-race, “you can’t pass anywhere.”

On his podcast released Tuesday, Dale Earnhardt Jr., who finished 18th in the All-Star Race, revealed VHT had been put down on the bottom groove for that event.

“The race was described as kind of boring,” Earnhardt said. “It was definitely one groove, there was no middle or high side for anybody to use … We’ve struggled with this racetrack at night, being a single-groove track. The bottom groove, the temperature of the track surface actually goes down. That increased grip, the grip’s going to better when the track’s cooler, and so everybody goes to the bottom. That’s the fastest way around the track. A guy just can’t make the track up on the high side.”

In the 2016 Coca-Cola 600, Martin Truex Jr. dominated the race by leading 392 of 400 laps on his way to the victory.
