The Ferrari 488 GTE Evo has been hit with a mid-event Balance of Performance adjustment ahead of the 24 Hours of Le Mans.
Confirmed by the WEC Committee on Thursday, both the GTE-Pro and GTE-Am variants of the car have received reduced boost levels across all RPM levels.
While the biggest reduction is at low revs, the change roughly equates to an eight horsepower decrease compared to the specification the Prancing Horses ran in the test day and opening day of official track action at Circuit de la Sarthe.
As part of the change, the Ferraris also lose one liter of fuel capacity.
The pair of AF Corse Ferraris were quickest in Wednesday’s qualifying session to set the field for this evening’s Hyperpole.
