On the research screen, at the bottom, you can see the bonus points that the car has, which come from the engine, fuel supplier, and tires.
In my particular case, there are bonus points that I don't know where they come from, such as reliability +1, tires +2, brakes +2. (The tire supplier is at -3.)
Where do these points come from? I didn't change my tire or fuel supplier, nor did I change DT or JD, and I already had those points in the previous season.
Can you give me an idea of what's going on, please?
thanks
