No Wedsley...its only a impression that I have.
I know that since the very beggining the BES Mod for rFactor was made looking very closely the FIA GT3 Technical regulations.
The authors of the Mod improved that even further for the version 1.2 of the Mod, made to rFactor, which I race in a League and enjoy a lot.
Unfortunately the conversion to GSC wasnt the most updated version of the Mod. It was the 1.0 version.
Still to me it makes sense the tyre model. When you make a huge spin in a real race, your tires are flat, you have to pit and change it, otherwise the car is not the same, it looses grip, it vibrates.
And watching F1, you see how the tires loose grip if the drivers abuse them, pushing too hard and sliding too much. The cars just loose grip and pace and the situation sink like a stone the more you abuse.
That is pretty much the way the tires in the BES Mod works, more or less.
As I said, it can be exagerated at times, specially with the Temps. But if you drive properly, you can manage that.
Is not like some others Mods, that you can do 4x360 spins burning your tires, get back to the track and do you personal best time next time around....
