A lowered car simply means that, well, it has its ride height reduced from its default position. I don't mind a car that is simply lowered, except when it's to the point where a great portion of the wheel is covered by the bodywork. (no, I'm not suggesting that I dislike cars like the Citroën DS, of which the rear wheels are partially concealed, that's a wholly different story, irrelevant to the case of lowered cars - those are really classy and elegant) I'm aware about the benefits of a lower center of gravity, in the form of snappier handling and reduced body roll, and it often makes the car look a tad sportier. We know that many manufacturers often decide to have the high-performance variant of their cars lowered for similar reasons.
A slammed car, though, does not simply refer to a car that has its ride height drastically reduced. It also means that the wheels' angle is negatively cambered. There are cases where slightly negative camber is a default thing, done by the vehicle's manufacturer for whatever intended benefits, but we hardly see the slant of the wheels, except when we get a closeup. Cases like this are perfectly fine to my eyes. What my eyes are not pleased to see are when the owner takes it too far, like this:
I don't like that. If we think of a car as a living creature, the wheels are like the limbs to me. Extreme negative camber makes it seem like the car's trying to imitate the way a spider goes, without looking like a spider in the very first place. It's just bending its limbs to say, "Hey, look, I'm a spider!", or something along the lines of that. And I don't like spiders, they scare me. I don't mind when "Spider" is part of the car's name though, that's another story.
Now, this is something which is not too bad:
Basically, most of the time, slammed cars are not pleasing to my eyes. Yes, it may provide better traction for the outside tires during cornering. (but the stress produced on the wheels may cause faster tyre wear as well, as far as I know) It's still ultimately silly in an unattractive way to me. I'm just stating my opinion, though. As
Harry6784 said, beauty is in the eye of the beholder.
As for my previous post, that was a rare station wagon produced in my home country being slammed, which I recently posted about in the
"You learn something new... - Cars you didn't know existed, until now!" thread. It's maybe not too bad-looking, but considering its rarity, I'm not pleased about what's been done to it.
Now, moving on:
