What This Means
These BoP changes aim to ensure parity across the grid and avoid any single car having a runaway advantage. Expect close racing in all three classes, where setup work and driver execution will be just as important as car choice.
The iRacing Petit Le Mans powered by VCO kicks off October 3–5 with five timeslots available. With the new BoP in play, the stage is set for one of the most competitive special events of the year.
