Guys, physics are changing, according to what Kaz said, after installing Spec 2.0. So the last race with "old" physics will be La Sarthe this weekend.
And when I thought I was getting adapted to the car, everything will change and will have to start the process again!
The physics arent changing for the whole game, just a few cars that had bad physics. Im very happy they are going to fix it(unless they make it worse).
