There is an acceptable way to cut springs, and there is a wrong way to do it. (Notice how I didn't say right way). The acceptable way is to use a die-grinder. The wrong way is to torch them. Why? Because heating the metal to such high temperatures changes it's molecular structure, thus hindering it from doing what it was designed to do properly!
Cutting the springs has some repercussion in terms of ride:
First and formost, you are altering the spring rate, and in doing so you can seriously hinder handling characteristics when driving over a bumpy surface. The car can become very unstable.
Also, you are shortening the suspension travel, making it MUCH easier for the car to bottom out. Thus, causing more wear on the shocks and shortening their life.
Sure, it looks good, but is that really more important that being safe??
Personally, I don't see any positive to cutting springs other than to impress people you really don't care about! If that nod or compliment to your ride is worth more than your car itself or perhaps even your head....
