I heard that I can cut and melt my stock springs...is this a good way to save money and lower my car?
NO!! Since your stock springs arent highly pro rate, you will be cutting off your springrate as you go. You will have a very stiff, often uneven, harsh ride and you will blow your stock shocks. You also can never revert back and if you screw one thing up you are basically screwed alltogether. Its a money trap.

What are the differences between different brands and genres of springs?
Well, generally springs, as they get lower, have a higher and higher springrate, which is how close together the spring coils are to each other - but a prorate spring gathers coils together towards the top and spreads out as they move down. The lower the springrate, the softer the spring, the higher the car sits.
Eibach is the choice spring for many people as they claim compatibility with stock struts, which is not all that far off, however they are still a highly progressive spring, even though they have a relatively lower springrage, and really are still putting a lot of pressure on your struts, its just unrealized since the springs have a lower springrate at the bottom.
Neuspeed springs and H&R springs are basically the "next step" up. They offer an allright ride, but they are a lot stiffer than eibach springs and a tad less progressive. They still progress down, except the coils are closer together. These offer higher performance.
There are others, like Suspension Techniques, Intrax, Sprint, BBK, etc. Most of these springs are as high or high of a springrate as the Neuspeeds, but some of them are notorious for sagging or being to stiff. However, The designs can be nice and great for the right application, like using S/T sport springs which are a very small drop.

Ok, enough technical jargon, what about the actual drop height of the springs...what are some different springs?
Here are some springs and their average drops (it varys from generation)
S/T Sport or Neuspeed Sofsport about a 1.0" drop, 3 finger gap
Eibach Prokits are about a 1.4" drop, 2 finger gap
Neuspeed / H&R Sports are about a 1.8" drop, 1 finger gap
Eibach Sportlines are about a 2"+ drop, 0-1 finger gap
Neuspeed / H&R Race are about a 2.25" drop, usually no gap, depends on strut
and the catagories for most sport and race springs from other companies (intrax, suspension tech, sprint are about the same drop as neuspeeds.

Thats nice, but my parents dont want me to lower my car, is there anything I can do that they might be OK with?
Sure, you can go with a minor drop spring like S/T Sport or Eibach prokits. Im sure you will notice the stance of the springs but your parents may not unless they just stare at the car or they always have something to compare it to. Most of all you get rid of a lot of that ugly gap.
--
I dont race, I just want people to see me and like my ride. What should I do?
The thing is, if you want the look and comfort and are not extremely concerned about performance, grab up the prokits or sportlines... they are just a softer spring to put it bluntly.
--
Whats up with that guy? Why would you lower a car just for looks? I want the best performance baby.
In that case, I would say go with Neuspeed springs. There is a noticeable difference in the performance, but the ride suffers more. The best performance springs are the high springrate springs, but your comfort is compromised. If you are really into it, go for some Race series springs, but I mean if you are really into it.
--
Ok, you mentioned struts earlier, but what do I need to do about them?
Well, on just about any car, if you replace your springs, your stock struts arent going to take it near as well, they cant stop the springs. First off, the springs are stiffer...no matter what. THe thing about eibachs is they still they arent uniform and they arent stock springs, and they will be stiffer. Eventually with any spring, especially the very stiff ones like Neuspeed, etc, you are going to blow out your struts...eventually. some people take weeks some months some can go a year but it doesnt matter - Ive seen people blow shocks with prokits just as fast as H&R Race, its still money you have to spend later if you dont do it now.

Oh crap, what kind of struts are good?
Some good struts are Koni yellows (the "best" by some) which have adjustable dampers on them (awesome) to match the rebound with the spring you are using or the situation you are in. They also have movable perches, which arent why you should buy them, but if you had to be in a height adjusting need situation, then it might be a nice choice. There are also Neuspeed Konis, which have 5 perches and not just 3. These cost more, but are better geared towards someone who wants to move the perches when paired with Neuspeed springs...
Before Konis, I had Bilstein HDs which are a non adjustable strut, they are my favorite and I say they are the best N/A strut, perfect for a budget street application, though the Koni Red had a bit stiffer ride.
KYB is another good strut maker that you hear great things about, but their warranty is null and void past a certain drop, I beleive 1.5. Still, for a lesser drop that you want an adjustable strut on, the AGXs remain a definite best value.
TOKICOs, well, I say they blow balls. I have grown to hate them the more I ride on them.. no offense to anyone with tokicos but they are best used in a low stress situation, IE with prokits that are on there solely for looks. However, If you choose tokicos for money, I would highly suggest getting the illuminas over the blues, so you can stiffen them up.
There are a few other options like the Bec Tec ride height adjustable struts, but I personally have not learned enough about them or seen enough people with them for an extended period of time to draw a conclusion.

How do you know that if you blown a strut or not? Do you feel any difference?
You will know when your struts blow. Your ride will be come very bouncy as your shocks no longer do their job. You will be very harsh over bumps... even with stock springs you will know. Its pretty bad. Basically what is happening is that your shocks no longer control how much the spring compresses, so when they are gone, your spring just keeps on boucning up and down until it stops. Thats it. All Im saying is that you should know.

What do you think is the best combination overall?
Now, as for that, my Ideal functional look and good ride combonation is Neuspeed sport and Koni Yellow. You can get your cars ride excellent with Eibach springs, and you can really get your ride down close to the ground with Neuspeed Race and Koni Yellow. H&R springs would be my next choice, and Bilstein struts respectively.
NO!! Since your stock springs arent highly pro rate, you will be cutting off your springrate as you go. You will have a very stiff, often uneven, harsh ride and you will blow your stock shocks.
