Just as an example, on the rear of my car, I replaced the stock springs with stiffer ones that maintained approximately stock ride height. I then pulled close to 200lbs out of the back of the car, and it was sitting about an inch and a half higher.

The springs were tangential end springs. I took a quarter of a coil off, and it was still a bit high, so I took another sixth or so and brought it back down to stock ride height, albeit much stiffer. They seat the same way when cut. When lifted, the springs are still considerably compressed so no risk of them falling out. I see no problems with taking a small amount off so long as you pay attention.

-Don't cut springs if it will change how they seat.
-Be mindful of suspension travel - going stiffer is a good idea, you don't want to be hitting your bump stops.
-Don't cut so much that they are no longer compressed when the wheels aren't on the ground.
-Be aware that with some types of suspension, you'll mess up your camber.
