Bank of America 500 race weekend at Charlotte Motor Speedway kicked off to a hazardous start on Friday. In efforts to help improve the on-track action at the facility, Charlotte Motor Speedway put down a special sticky substance in the turns to try and help widen out the groove. The substance, most commonly called PJ1, worked well in Turns 1&2 but caused mayhem in Turns 3&4.
In Friday’s lone practice session, several competitors got loose coming off Turn 4 and slammed the outside wall. Dale Earnhardt Jr. was the first to do so, pancaking the right side of his car, thus forcing the team to bring out a back-up car.
