Ok I see the point that you stole that car, but you are taking thrifty a wee bit too far, when you want to cut the springs, for me. I told you I hate seeing cars lowered for the very reason you just mentioned. When it is not done with a professional respect it ends up riding and handling like a hack job.

Anybody who buys a car, lookout for hack jobs of the interior or wiring and they usually walk away, like yours truly! The look of stock cars are figured around a mass audience not just a few individuals. Aftermarket is tuning for that other "selected" market of tweakers in most of us, restorers or bargain hunters!

I agree that the front end looks to high but then the back end has probably sagged and any kind of load or none will result in that look.
You could try lowering the front first and that may help your minds eye.

Jacking around with springs is like playing with a box matches. Sometimes the first try does not light...right nicely.

First of all springs are not "simply" cut when they are made. They are flat across the ends and squared to the compression axis for a reason. The material is tapered smaller along with the end as it turns so the rate of compression is graduated. The temper of the coils change within the coils length and pressure exacerbates those stresses.

Blacksmithing or now, heat treating and metallurgy are bonifide trades. You do not want a spring to "bunch" to one side. These are not ball point pen springs and are not contained in a barrel and a cracked spring....well?
After springs are made they are tested, compared and grouped in sets or "batches" by their steels reaction specfications. They can look and measure dimensional the same but have different part numbers. The responses are sold to be predictable for a reason.

That said, change your springs as you will, but remember that most time while you are driving you expect the car to act according to what you expect it to do and "that" can make a difference in surviving the unexpected things we call, accidents.

I suggest you forget the torch and tape measure. Identify what spring you have and how much load it takes to change it to the height you want and take them around looking for the spring that holds that weight at that height with a spring rate you like for the rest of the travel after the preloading. Stiff or soft and shop for the closest stock one in the diameter needed.

It will be the least expensive and the one with the best reputation with suspension professionals.
With the gazillions that are made there must be boat loads of information around. Probably a half dozen cars in junkyards with them with cross references.

Anyway that is what I would do.
I have three cars that I have changed springs around within them to get better loading characteristics. I started out with two from IPD since they were the closest professional tweakers I knew.
Their rear overloads were a little too stiff for a sedan but almost right for my station wagon empty and just fine when loaded up! The standard unabused 86 wagon springs are better under the 84 sedan. I need another set for my 91 as sits a little low and squashes too easily.

I think it is back to a box of mixed up matches as it is not a waterproof affair!

Good luck
