A coil spring is like a torsion spring, in that by varying its length it will become weaker or stiffer. Shortening a coil spring will increase the rate of resistance. Building a fixture and putting the spring in press, heating a portion of the coil till red and compressing the spring enough to reduce the length at full extension may do it. Be prepared to reduce the bump stops and check for coil bind at max compression. Also take this as an experimental attempt to gain what you are after with a cheap and dirty method, realizing the integrety of the spring may be affected.

Okay - technically when you cut springs you increase stiffness (which may or may not work with the current dampening rate of your shocks) and reduce the distance to the bump stops so have a greater chance of bottoming out. Also, you need to get the angle correct on the cut so that it mates with the top mount properly.

Do not cut the srpings... on any car..... ever.......
The end result is just another POS safety issue laden car drivng down the road swirving into my lane. Me no likey.

For a stiffer spring w/o bumpstops i always believed that you needed a thicker spring, but i may be wrong.

How do you figure this? the KG Rate of a Spring is set by the thickeness of the Coil... just because you cut the spring it will not make it stiffer.... Cutting it does not make the coil thicker now does it... unless its a muscle like a *****

Read the thread that I linked you to earlier here. Thickness is not the only element. There is the composition of the metal, the density, the way in which it is coiled, whether it is linear/progressive, etc.

Cutting the spring takes away coils or parts of coils. Each coil has a certain amount of "soft" give as you compress it.
Try this get your 3 beam cannabis scale out. Find a pen spring and measure the force it takes to compress it 1/4". Then cut off a coil and check it again.
To get the same travel on a cut spring you are moving the remaining coils farther into the stiffer part of their travel.
We lowered a Bug-eye Sprite front end by cutting the springs we were surprised that it made the ride much firmer.
