I have a simple question. I cut my front springs last weekend and was pretty happy with the way it turned out. Now I need to know if it is possible to cut the rear springs. The reason i ask is becasue my stock springs have the PIG TAIL on both ends so can you cut one of those off. I know its cheap to buy new springs but I don't want to hassle with buying the new springs and it not give me the ride height i want it and i have to return them and go with another spring. So this way its free and i can get pretty precise.

If it is possible to cut the rear how much will I lower it if i cut 1 coil out.

Thanks for the help

If they are pigtailed you can't cut them, they won't seat on their mounts properly after the cut.

You can cut them, but they drop it a LOT when you do that... I ran mine for a short time like that, but they were too soft to be that low, so I was hitting the bumpstops constantly. Now I run 5"x11" single-pigtail 175# Hyperco's and they work very well with the way my car is set up.

Auto parts stores carry these little brackets that compress 2 coils. You could try those on both sides, and not have anything permanent. the coils will still seat.

Try just heating a coil close to the top - some on each side of the chosen coil to keep the spring tension balanced. Have partial car weight on the springs when you heat it red, so the spring will sag a bit as you heat it. Do it on the next to last coil so the remaining coils will carry the weight. This way you retain the "pigtail" and drop the height too.

for the way you want it is best to get the clamp from Autozone and clamp it down to the height you want and it cheaper taht way

If you do this it will ruin the temper in the spring and it will keep sagging. That's if you can get them to "sag" the same on both sides in the first place.

If you do this it will ruin the temper in the spring and it will keep sagging. That's if you can get them to "sag" the same on both sides in the first place.That depends on how you cool them... if you cool them very slowly, the temper will be fine. Just don't cool them with water and they shouldn't be a problem.

The best answer though is new springs with rate of about 150lb/in as lowering springs need to be stiffer than stock to keep it off the bumpstops.
