DH, There is only Balance of Performance on LM-GTE class cars, as they are based on production cars that are fundamentally different from one another, thus necessitating the BoP to level the racing.

The 919 EVO uses active aerodynamics, ground effects, tyres that can handle the additional stresses, weight reduction including removing headlights, and unrestricted fuel flow, which makes it about 10 second faster around Spa than the 2017 919 in qualifying trim.
