I don't have a Wheel, but that should be normal, trygetting a more stable car-
I think-correct me if I'm wrong.
With force feedback wheels, uncontrollable shaking while trying to drive in a straight line is usually a sign of a potentiometer that is either bad, or going bad. When this happens, the pot is unable to tell the force feedback that it is in the "center" position, causing the force feedback to shake back and forth as it tries to "find" the center position.
You'll probably have to replace the pot, or just get a new wheel.
A DFP cost $150 brand-new, don't know what they go for these days. The G25 is $300.

Good & Fault:
My DFP is new, shakes like hell when going 350 with a GT-ONE, is it broken? Yeah, right
How else is a wheel going to relate to a human what is supposed to be going on with a car at extreme speeds?
