Okay, recently I started using a driving force steering wheel while playing GT4. I noticed that if I am driving a race car once I get up around 125mph or faster, the car wanders all around on the straights. The steering wheel turns side to side really fast until you slow down costing you probably 5 mph even if you don't slow down just because the car jerking from side to side slows it down. It only happens while you are going straight and if you turn the wheel it stops. This problem seems to be worse at the Nurburgring and Sarthe but it is a problem at all the tracks. This is only a problem with race cars, if I drive street cars there is no problem. I never encountered this while using the DS2 so I am wondering if it is normal for racing wheels or if it is a problem with the setup on the cars. Thanks.
