Eliminating body roll is not necessarily a good thing. You want s little roll to help plant the tires in a transition. Basically too stiff of a suspension is not necessarily a good thing either. Adding sway bars is another area where people get carried away not understanding how a stiffer bar will affect dynamics.

I do agree that most people lower for looks primarily, and I do agree 100% it looks a hel of a lot better, but I also hear plenty of misinformed statements that slamming a car down 3 inches makes it handle much better ( not necessarily here but out in the rear world I hear this a lot)
