Yea but who decides what's realistic? Anyone here drove an actual F1 car lately? 1/1 spring is just undriveable and 11/11 is like on rail. And it's basically a difficulty slider as you said. So as I get better on a track and faster, I need to turn down the spring to make me slower?Spring stiffness. Basically keep it 7/7 or 6/6 to get some realism. You can basically use it as a difficulty slider haha
