Stock struts vs gti struts

worst way you can do it would not recommend

hence the "desperate"

Jokes aside, if racing on a budget, you can use this technique to work out what spring rate is needed if they're too soft (on a test day) provided you have adjustable damping and ride height.

But for street lowering, yeah....

ya the main problem i have with 'cutting' springs is they lose their actual 'spring rate' of the original spring. and most people seem to cut too much out lol

As a basic explanation, spring rate of a coil spring works like this:

directly propotional to:

> elastic modulus of the steel used
> wire diameter

inversely proportonal to:

> coil diameter
> number of coils

so, if you reduce the number of coils, the spring rate increases (spring gets harder).

Another way to think of it is that if the spring had only 1 coil, you can imagine you would have a LOT of trouble compressing it (exactly analogous to trying to bend a very short bar). If you have a very long bar of the same diameter, you can bend it very easily.
