The dead coil helps keep the spring located when the suspension is at full droop. If you cut it, spring rate will be unaffected, but you may introduce rattles into the suspension. Cutting the coil will likely not show any lowering either.

True sometimes, but not always...

Not true. Dead coils are often used to set ride height.
Dead coils may be used to set ride height... poor engineering when the manufacturer can have appropiate spring rates. aftermarket spring producers are more likely to use that crutch.
Cutting a coil will likely not result in noticeable lowering as these springs will generally have higher rates than the factory units (introducing preload)'
Depends a lot on the weight of the power plant and acessories. .
The way I've seen aftermarket spring companies adjust for small heights like the thickness of wire differences is to just change the free length of the spring another 10mm or so. Using dead coils isn't the way to do it. They're only used to make a flat resting face which is important when the spring is very weak, long, or the load is very heavy. Sometimes there will be two coils at the end to support the top face, especially if the spring is strong.
