Whenever you negotiate any turn with your car,because of the geometry of the front suspension on G bodies,your suspension moves the tires into a position that hinders the turn you are trying to make. If you do the modification I've described,your suspension will move the tires into a position that helps the car turn. This means you can get away with less spring and less sway bar and still have a car that can level out a corner pretty well. When your suspension fights the turn you are trying to make,it does it when the control arms move during the turn. To stop the crappy suspension geometry from hindering your turn,you need to hinder the apward and downward movement of the control arms. This is typically accomplished buy using stronger springs and sway bar. This leads to a more harsh ride. If you like the ride comfort of your car currently, it will still ride the same after the modifications I've described but will turn better with less steering input.
If you have the factory style outer tie rods and the factory spindles,you have bump steer.
The suspension is designed in a fashion that purposely hinders any turn you try to make so that you are less likely to cause the car to spin out. The engineers purposely put the suspension geometry into a position that moves it away from working OK.
