Too bad you don't have force-feedback (you're running it via Wine?). It helps a lot in understanding and feeling the weight transfers of the cars, thus helping you (even warning you) in many cases.
Other than that, set your G25 rotation to 720 degrees both ingame and in the drivers and also set the Wheel Compensation to 1 ingame. This will make sure your wheel wont't turn more or less than the intended by the devs steering of each car.
Centering force might also killing you
