Overall characteristics stay the same tho. BoP is mainly tweaking. Unless a car is completely off, there isn't a lot that changes.To be fair, BoP and different tires mess up the cars so bad IRL that they are very different in almost every race so it´s kind of pointless to compare them to their simulated counterparts, that is until Blancpain, FIA, IMSA or ACO start co-developing these kind of games....
