Signed up just to say “Yes, me too”.
I have the CSW2.5 and recently getting into rfactor 2. The FFB in that is amazing but the wheel deck on the art cockpit just isn’t up to the job and the lateral shaking issue you described is a real problem on anything higher than around 60%.
Did you get round to using the longer seat rails to add extra bracing? If so would be interested to hear how you got on.
