I've had the same car now for about 1k miles, and I dropped mine in this morning to have the same thing looked at. I don't feel confident putting this car into a corner under any pressure - I've lost traction a couple of times in the dry, in the wet it's very bad. I am constantly wiggling the wheel about 1 degree left/right while I am driving straight just to feel a "connect" with the road.
I also have this constant vibration/hum that I feel on the wheel, high speed left hand bends are my major issue, the car seems to drift to the right all the time.
Having said all this, I normally drive a bike and nothing takes corners like a gxr600 so maybe I'm just expecting too much from a road car?
