I was looking at the Cusco sway bars, i noticed that the front and rear bars come in two different sizes, which one would be best for my needs? Which one would give me the best handling improvements?

 

Depends on what you are using the car for. Most drivers reportedly wish to lessen understeer or push. This can be accomplished with varying degrees of success by eliminating the front bar, down sizing the front bar, increasing the diameter of the rear bar, or any number of variations to that theme.

Driving techniques are an equally important factor in minimizing the undersireable consequences of understeer.
