You are way better off buying new lowered coils, as when you cut the coils you increase the spring rate and really stiffen the ride. My .02 cents

Re: cutting coils?

Cut the bottom of the front coils since the top of the coil fits over a sheet metal boss to keep it centered. You can't cut the rear coils since they need both bosses to mount them to the frame and trailing arm. You can heat the rear springs to make them sag. Old school guys have been doing it for years.

Thanks thats what I thought, do you just heat them up with a torch and they shrink?

Re: cutting coils?

You have to cut the bottom. The top is pigtailed, the bottom is not.

1 coil equals about 3 inches. I've cut a bunch of them and been happy with the results. Cut em first, if you're not happy, then buy drop coils.

Re: cutting coils?

On the rear I just heat them with a torch in the middle. I move it around to different locations to try to even it out a bit. Once it starts to sag you have to watch it closely to make sure you drop the same on either side. I have run coils like that in hotrods for years without any problems. I don't use them as daily drivers though. This is a cheap fix when you don't have the cash. I am running bags now and really prefer them since they are infinitely adjustable.

Please read this.....

DON"T heat your coils. If you can't afford to do it right, wait.

The only way to control the amount of drop when heating coils is to place a fixed object (like a block of wood) under the suspension so it will only collapse a certain amount.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
