Background

Road America, where the race was held.

International Motor Sports Association's (IMSA) president John Doonan confirmed the race was part of the schedule for the 2023 IMSA SportsCar Championship (IMSA SCC) in August 2022.[1] It was the tenth consecutive year the event will be held as part of the WeatherTech SportsCar Championship. The 2023 IMSA SportsCar Weekend was the eighth of eleven scheduled sports car races of 2023 by IMSA, and it was the fifth round held as part of the WeatherTech Sprint Cup.[2] The race was held at the ten-turn 4.048 mi (6.515 km) Road America on August 6, 2023.[3]

Breaking tradition, IMSA didn't hold their "State of the Series" annual press conference during the Road America race weekend. IMSA moved it to the Michelin Raceway Road Atlanta race weekend.[4]

After the 2022 season, the venue was renovated. Drainage areas were upgraded, the pitlane was paved, and the track was resurfaced.[5][6]
