People do it for preference on looks. I tastefully lowered car (i.e. not too low because that just looks stupid) does look more pleasing to me. Having said that, I won't go out of my way to replace suspension components to get a "slightly" improved look. When the competition package comes out, the subtle drop will be perfect IMO.

Lowering can also result in potentially better performance if done correctly but the vast majority of those who do it are only interested in looks... they don't get performance benefit and can actually degrade performance for the sake of looks. However, done right with a lower center of gravity and a properly tuned suspension and you can likely get improved performance.
