The front stabilizer bar

Stabilizer bars are an important part of a vehicle's suspension system.  Also called the anti-sway bar or anti-roll bar. The purpose of  this bar is to try to keep the car's body from "rolling" in a sharp turn. A stabilizer bar tries to keep the vehicle's body flat by moving force from one side of the body to another.

When you now go into a turn, the suspension member of the outside of the turn gets pushed upward. The arm of the stabilizer bar gets pushed upward, and this applies torsion to the rod. The torsion them moves the arm at the other end of the rod, this causes the suspension on the other side of the car to compress as well. The stabilizer bar keeps the vehicle more flat in the turn.

If you don't have a stabilizer bar , you tend to have a lot of body roll in a turn. If you have too much front stabilizer bar , you tend to lose independence between the suspension members on both sides of the car. When one wheel hits a bump, the stabilizer bar transmits the bump to the other side of the car as well. It's best to find a stabilizer that reduces body roll but does not effect the independence of the tires.

If you are inside a car making a sharp turn, your body gets pulled toward the outside of the turn. The same thing is happening to all the parts of the car. So the part of the car on the outside of the turn gets pushed down toward the road and the part of the car on the inside of the turn rises up. If you take a turn fast enough, the tires on the inside of the turn actually rise off the road.

A good stabilizer bar will help prevent more weight being put on the outside tires and less weight on the inside tires, which reduces traction. It also messes up steering. What the stabilizer bar will do is help the body of the car stay flat through a turn so that the weight stays distributed evenly on all four tires.
