DAYTONA BEACH, Fla. – IMSA has announced the realignment of several upcoming dates on its schedule, including shifting of the Labor Day Weekend six-hour race from Watkins Glen Int’l to Michelin Raceway Road Atlanta, and the GT-only event from Lime Rock Park to the Charlotte Motor Speedway ROVAL.

Michelin Raceway Road Atlanta will host the six-hour IMSA WeatherTech SportsCar Championship race on Sunday, Sept. 6, with three other IMSA-sanctioned series that all were previously scheduled to compete at Watkins Glen also moving to Michelin Raceway that weekend.

A four-hour IMSA Michelin Pilot Challenge race will be held on Saturday, Sept. 5, with doubleheader races for both the Porsche GT3 Cup Challenge USA by Yokohama and Lamborghini Super Trofeo races also planned for the weekend.

The Charlotte Motor Speedway ROVAL will host the WeatherTech Championship GT Le Mans and GT Daytona classes in a 100-minute race as part of the NASCAR event weekend, Oct. 9-10, at the facility. This event will replace the Lime Rock Park race previously scheduled for Sept. 11-12.

“When Speedway Motorsports CEO Marcus Smith first envisioned the ROVAL, part of that vision included bringing new series to the track in addition to our classic NASCAR Cup Series events,” said Greg Walter, executive vice president and general manager of Charlotte Motor Speedway. “We look forward to working in partnership with IMSA to provide a unique perspective to race fans and a one-of-a-kind challenge to the drivers who will be tasked with tackling this technically innovative course.”

Michelin Pilot Challenge, which also was scheduled to race at Lime Rock Park, instead will have a doubleheader of two-hour races at Mid-Ohio Sports Car Course on the weekend of Sept. 25-27. The GT3 Cup Challenge USA by Yokohama will have three events per weekend at Mid-Ohio and the Motul Petit Le Mans weekend at Michelin Raceway Road Atlanta on Oct. 14-17.
