Oooh, as far as I know, thats a bad idea cause the factory springs are progressive, but someone else probably knows better than I.

I have a book, "Chassis Engineering" by Herb Adams which for Mustangs, other he makes that suggestion is a very good book. Its a bad idea for Mustangs because they come with soft springs and stiff sway bars. You're better off going with stiffer and lower springs for better handling, plus they aren't very expensive for Mustangs anyway.

If you want to try it, do it anyway from what I've heard it doesn't work. But trying you would just lose the work.

Get a "C" springs with rears cutted one loop

Dont cut springs.

You may be cutting off the variable rate portion of the spring, and thus hurting ride. Also, the spring will be too soft at the new height, and will bottom out more often.

BUY some new H&R or Eibach springs (more expensive ones, see other posts) and be done with it.

Finally, if you do cut the springs, use a cutoff tool. Not a hacksaw (takes forever), or a torch (cause the heat will ruin a psring and make it sag over time).
