This may be wierd, or i may be looking at this matter a bit too much, when when i am turning and hit a bump, the front of my car feels fine, but the back sort of steps out a bit. almost like the car is twisting.. in a straight line it feels fine. i highly doubt that it i something wrong with the chassis, but could it be something with the suspension? the car has done about 4 drifts in its lifetime so could that have done something? Help a worried e46er!
