Don't really think its the preload itself. Cause preload only comes into effect in the short time between braking, turning in, and getting on the throttle. Its activing during that turn in phase. It's probably got something to do with preload effecting power/coast settings. So I think I'm going to have to tweak those some. Someone said somewhere, that if you just set preload to 0, it will be back the way it was, but I'm not too sure about that. Otherwise devs would've set it to 0 so it had a neutral effect. Besides, increasing/decreasing it, effects oversteer/understeer during that turn in phase.
