Have you ever seen the A-TEAM? Who is driving the car? Yes it is B.A.
Go watch youtube and see how he drives a car. It is insane. The steering input B.A. gives while driving the car is too much. Even on the straights he is putting a lot corrections to the cars steering.
In simracing you will have to try to steer as less as possibly needed. So when exiting a corner, let the wheel move to its neutral position instead of putting force on the wheel so that it can not turn fast enough to its neutral position.
Also when cornering try to steer in one line instead of making corrections while turning. This will make the car more stable.
