Hi/braking problems

[fabio93bg]

Hi all i'm new! i come from gpbikes and decided to race karts as well magnificent simulator but i have one problem: for example with shifter kart when i' m braking and using one hand to downshift and i have only one hand on the wheel i cannot control the large "vibration" (rapid right and left) that suddently happens on g25 (and so on the kart virtual wheel). i tried a lot of wheel' s and force feedback ' s setting but the problem still stays. is it my problem (not from the settings but driver's problem)? it happens not only in brakings but in general using one hand on the wheel or no hands (strange example: if i turn right just a little and leave the wheel it beging to go left-right-left-right like crazy in a not-natural way of force feedback. sorry if i couldn' t explain better thanks in advance

Normally some shaking occurs when going in a straight line (but not much).
Are your ingame FFB settings too high?
