Step12:
Reinstall strut in upper mount, then rebolt to spindle. Reinstall brake rotor and caliper. Reinstall wheel, jack car up, remove jack stands. When lowering the car down on the jack, go slowly so ensure that the jack will clear the newly lowered body. If there are issues raise car back up and use blocks so that the jack can be safely removed.
Rear Spring replacement:
Step 1:
Jack up rear end

IF YOU WANT TO CUT YOUR SPRINGS, CONTINUE READING:
Cutting your springs is a perfectly legitimate way of improving the looks and handling of a Mustang. It's a proven fact that a properly modified factory spring is better than 90% of the best/most common aftermarket springs on the market. For auto-x use they set the in-lb rate almost perfect without going to a coil-over/k-member/tubular control arm setup. Don't do it unless you change your shocks/struts, or you'll bounce all over in short time.
To get the proper height, start at 3/4 of a coil all the way around, and let it settle for a few weeks. It will most likely drop up to 1/4" during settling alone, aside from what you removed. DO NOT USE HEAT TO CUT THEM!!!!! Try to use a hacksaw(the slow way) or a cutoff wheel(the smart way) jsut try not to let it get too hot. If you want to go lower, do it 1/4 coil at a time, at the most, and let settle again for a few weeks again. It sucks to cut too much, because there's no way to put it back. My sig pic is with 18's and 1 1/4 coils removed.
Step 1:
With spring removed, mark where you want to cut. It's best to cut less and go back to cut a little more than to cut too much
Step 2:
Wearing gloves and safety glasses (full face shield is preferred), use cutoff wheel or hacksaw to remove coil, DO NOT USE A TORCH!:

Step 3:
Reinstall newly cut spring.
That's it for now.
