The move was described as "back to the future" by IMSA president John Doonan as sportscar racing heads into what is predicted to be a new golden era across the North American series and the FIA World Endurance Championship.
Doonan said that the announcement of the move at Daytona on Thursday ahead of the opening round of the 2022 IMSA season this weekend "makes the hairs stand up on my arms".
