The tentative schedule for the 2020 IMSA WeatherTech SportsCar Championship’s has been further revised and firmed up, with date changes for three of the rounds.

The Sahlen’s Six Hours of The Glen event, has been brought forward one month to be held on Labor Day weekend, Sept. 3-6 and as usual it will feature all four championship classes.

The GT Le Mans and GT Daytona classes will remain in the Northeast through the following weekend, moving to Lime Rock Park in Connecticut for the 2hr 40-minute Northeast Grand Prix on Sept. 11-12.

Then WeatherTech Raceway Laguna Seca will now host the penultimate round of the season, the Hyundai Monterey Sports Car Championship, with all four classes on Oct. 30-Nov. 1.

“These revisions to our 2020 schedules put all of IMSA’s stakeholders in the best possible position for success,” said IMSA president John Doonan. “They are also the result of the ongoing spirit of collaboration with our promoter partners.

“Moving our Northeastern events into September should pay dividends from the standpoint of weather. WeatherTech Raceway on Halloween weekend also has the potential to be spectacular and will set the stage for a thrilling conclusion at Sebring.”

Meanwhile, the 2hr40min race at Sebring has gained Cadillac as a title sponsor and will be shown live on NBCSN at 5.30pm ET. Next week’s Daytona race, the WeatherTech 240, will also be live on NBCSN, coverage beginning at 6pm ET.

Doonan commented: “Prime time, Saturday night windows on NBCSN are extremely valuable and provide all IMSA stakeholders with an opportunity to showcase our sport to a significant audience.”
