Hey Shakes take no notice of some of the gooses on the forum. A lot of them like to blow their trumpet, just so they can hear the crappy noise that they make.
Most of them like to spew nonsensical diatribe at any given opportunity. Most of them wouldn't know what a coil over is, even if you were beating them to death with one.
To help answer your question.
The coil spring on a coil over is basically the same as a standard setup, just a smaller width, so to speak.
If you adjust the coil over by the spring seat to lower the height of the car you will run into all sorts of problems.
The spring needs to be held captive between the top and the bottom seats at all times. If you jack the car up and let the suspension sag to its full droop the spring should still be held with enough pressure that it doesn't have any free movement up or down.
If you wind the spring seat down to lower the car, you will find that the spring will come loose on full suspension travel. This can cause all sorts of damage if it happens and the spring doesn't sit back into the seat correctly.
You also have to understand a spring has a rate assigned to it and by backing the spring seat off makes the spring operate out of its assigned rate, this is bad.
Next problem is that if you lower to far you will end up putting your shock absorber out of its effective working range, this is VERY bad as your handling will go down hill at a rapid rate. This can also cause damage to other suspension components.
You can add Tender springs to the coil over that will give you a little more adjust ability to the system or you can purchase a coil over that has two adjustments on it.
One for the coil spring and one for the height of the strut itself, this system is the easiest if you are simply looking at getting your ride height to a set level and not looking for handling.
If you know some one that is a certified welder you can make your own coil overs that will be far cheaper and far better than a lot of the crap that is on the shelf.
