Before you go cutting your OEM springs, Please take a couple minutes and read this very important explanation on why you shouldn't.
Let's start with the basics.....................

NUMBER ONE: RESEARCH Is Your Friend !

NUMBER TWO: Cutting a spring will give you a better chance of hitting a bump and popping the spring seat out of the perch.
All Produced springs have a flattened transition on them which lets the spring seat correctly on the shock/strut perch, and the rubber cup of the top hat.
If you cut a spring on the bottom, the flat spot is now gone and the angle of the coils will not hold in their proper indentation......which can create a very big and noisy problem when riding down a rough road, and may abruptly position the whole spring out of it's perch and wedge it at an angle overlapping the shock cup.
This will make the car's ride height uneven and dangerous when steering.

If you cut the top of the spring off, The combination of angled sharp metal and a rubber Top Hat will cause gouges in the rubber and evenly complete destruction, Then you will have a loose spring and much bigger and more expensive problems on your hands.

& NUMBER THREE: A stock, cut spring will still have the stock spring rate. Aftermarket lowering springs have increased spring rates, usually about 25-30% stiffer than stock so it won't bottom out. If you cut stock springs, it will bottom out very hard and give a hellish ride. You'll blow your shocks and your car will ride ghetto. If you only want to lower your car and you don't have the funding to afford Tein, Neuspeed, or H&R, get some cheap ebay coilovers or invest in some Drop Zone Race springs. People who cut their springs to lower their cars, are cheap asses and shouldn't even be modifying cars IMHO. BUY SPRINGS and lower your car the right way the first time!!!!!!

& NUMBER FOUR: The biggest problem w/ cut springs, is that you have no Idea what sort of spring rates you have after you do it. Also, there is NO WAY to cut both sides so they come out w/ the same spring rate. This will give your car dangerous handling problems.
Imagine you slam on the brakes to save your life & the car leans to the Left side, causing your car swerve into oncoming traffic or to the right where there is a drop off from pavement to grass/dirt shoulder and you bottom out tearing up your oil pan or something worse.

Your next problem is that taking a spring & removing some of the coils will cause the spring to become much stiffer (less wire = harder spring). This is why your car will be Hella bouncy. The severe stiffness of the springs can't be overcome by the shocks & will cause them to be destroyed. Now you need new shocks, and that cost much more than really good lowering springs.

Have you ever run around on bald tires in the front, Then accelerate quickly on a road like Dale Mabry. There are so many potholes and uneven levels in the road, You Tend to loose control very easy and could cause an accident.
Driving in the rain is even worse,....................(And Rainy Season Is right around the corner).
Uneven Spring Rates are the same Idea......If you have a stiff spring on one side and a weak spring on the other, Control is going to be a very hard thing to come by, especially on an uneven road!!!

Don't risk the reliability of ride, continuous Cost of new Tires, Replacing Shocks, Having an accident, damage to the rest of your suspension components, insurance rates if you get into an accident that's your fault, having the cut spring popping out of the perch because the seat is now at an angle instead of a flat surface like purposely created on all factory/aftermarket assembled springs, Etc...........

I'm getting tired of typing, But if that info didn't scare you into not cutting springs, I have a lot more info that I can Quote or print off on a scanner and post it up.

Best Of Luck with your decision!
