My vehicle already has anti-sway bars, why should I upgrade?

There are many reasons to upgrade your factory bar depending on the application.  If it is a truck or SUV, it can be made to handle like a passenger car by offering flatter cornering and quicker response.  If it is a large passenger car, it can be made to handle like a sports car for the same reasons and it adds more stability on the highway at speed, especially when those big trucks go by.  Finally, if it is a sports car you will achieve flattering cornering and if installed as a pair (as intended) you will reduce understeer and have a more neutral handling vehicle.
