Re: Cutting stock spings. Springs are made using steel that has been heat treated to expand and contract at a specific rate. If a spring is heated for cutting, it will sag. it's practically impossible to cut heat treated (very hard) steel without creating heat.
If you look at a spring, you will notice two things. First, the spring coil diameter goes from thick to thin. Second, the spring goes from the coils being close together, to being far apart. Both of these things are done to allow a spring to have more or less stiffness at a different point of suspension travel. So, if you cut the spring, you will either loose or gain stiffness depending on which end of the springs coil you cut.
I have been around long enough to remember the days when this was the only way you could lower a car because there were not aftermarket springs available on the market. Cars always rode worse, but looked better. Today, it isn't worth all the work to cut springs, since there is a huge selection to chose from, at cheap prices, and you can improve your ride! |
