I've cut a lot of mustang springs. I'd say about 90% of the foxbody mustangs you will ever see that dont have coilovers have cut springs. For this particular application you cant tell a difference when done right. just clip a 1/2 a coil at a time, use a cutting wheel, dont leave any rough edges and replace your rubber cups. It's pretty common in the domestic world, at least for cars going in a straight line.
