Pretty sure BoP was introduced in GT:6 so it isn't the first time its been used, I mean seriously they have introduced fuel usage and tire wear in daily races yet not once have I had to worry about destroying my tires or needing to pit for some go-juice, Now maybe if the wear and usage was increased significantly it might help even the playing field, (BTCC for example FF can heat and use their tires better to begin with, FR needs time to warm them up so they work better later in the race) Add in the wear and you'll get over/understeer where applicable.
But as things stand right now if you want any chance of a top 5 finish you need to be in either
Gr3
Beetle
Porsche
Gr4
Scirocco
Megane
One might think in this modern world where a server connection is mandatory they could fiddle with some numbers on the fly to even the playing field, Comes to something when Renault are more competitive in a game than they have been for the past 5years in F1
