You may have to cut. The parts manual takes you through a calculation of what type of spring you should have. It's by weight and what options you have. If you have A/C you'll need a heavy spring. Also, you need to find the insulators that go on top, otherwise you'll have noise.
Once you've installed the springs, if you don't like the stance, you'll need to cut the springs. Someone may have a table that indicates how much to cut to get an inch drop.
You might also find that one side is higher than the other. You'll need to cut the higher end to get the car in balance.
I would worry more about getting the right strength spring rather than the height. You can always cut to get down to the stance you want.
The parts places can go from the part number in the parts manual to the replacement part. I think I ended up with Moog springs on my daughters T/A. One side had to be cut to get the car balanced.
