coil springs are designed for coils to touch, it helps give the spring their progressive nature.

yes, when 2 coils sit on eachother it changes the static poundage of the spring. as you corner right, the right spring will compress and the centre coils will sit on eachother meaning that the active coils (upper and lower) are now controlling the spring rate.
On the left spring it has the opposite effect. It gives the spring the ability to behave differently under different loads which improves handling.
Most road springs have lighter lower poundage coils on the upper and lower sections and much stiffer coils in the centre. over smaller bumps the upper and lower springs control the spring softly, but as you enter a fast corner where you want less body roll these parts of the spring will compress under load and the centre coils will be in play, which are higher poundage and will give a lot less body roll.
The upper and lower coils are known as dead coils as they do nothing!
Progressive springs are produced by varying the main diameter of the coil.

And no they shouldn't touch at all.
If the coils are touching, there coil bound giving fook all movement=poor handling

Bilstein must be making their springs incorrectly then, also it seems Eibach springs are leaving the factory incorrectly.

Not at all, 'progressive' has very little to do with the coil wire diameter and more to do with the way the spring behaves under compression. As the coils go coilbound the static poundage of the spring changes giving the spring a progressive method of compression. The more the spring is compressed the higher the static poundage becomes.

LMFAO at they are meant to touch!!
thats the most stupid thing i've ever heard.
once the coils touch you have no suspension it's solid.

Mine used to sit like this on my old Corsa and they worked fine. Like Stavs says:

Since I'm not sure I'm not giving any more advice, but if it's only the two middle coils touching you'd still get a fair bit of travel.
Still not as much as I'd think you should be getting though...
What are they saying on corsa-C?

So your coils should touch then, giving no spring movement, making the car bounce about over bumps instead of letting them spring do the work

It's fine, my H&R's are like that.
Dave A is right
