Shortly afterwards, IMSA announced that the method it implemented in GTD at the Daytona 24 Hours was too complicated to replicate for the remainder of the season and so, in agreement with the manufacturers, it reverted to last year’s more traditional system.

The engineers used first order parameters of weight, power and aerodynamic efficiency to balance the cars. Toyota, however, was better than anyone else in race conditions, notably on second order parameters such as tyre wear and strategy, and won the opening races comfortably.
