vujade, The ride is phenominal. Comfort level is very high, which is desirable with low-pro tires!
The pic in my earlier post clearly shows a 1302 strut.
No spring in the world has an adjustable spring rate. A springs 'stiffness' is a product of material and dimension.
Spring stiffness (uniform open coiled helical spring within elastic range)
= Force / Compression, measured in Nm^-1.
This is linear (y = mx + c), i.e. double the force, the amount of compression will double too. This can be applied to the springs used with most aftermarket struts. This much can be cofirmed by appearence.
The stiffness of the Eibach springs, however, is second order (y = x^2 + x), due to the change in the geometry of the coiling. The Force / Compression curve will show that the rate of change of compression decreases with respect to an incremental increase of applied force. This makes all the difference!
The height of the lower spring plate is adustable, this only determines the height of the vehicle at equilibrium. On the road, the amount of spring compression is determined by the mass and position of the centroid (the point where the mass of the car is believed to act) Move the centre of gravity and back and forth and see the front and rear spring compressions alter. e.g. Move the centroid forward, raise the front lower spring platforms to compensate for the resultant change in stance and you've just softened the response of the front-end (after you have increased the damping (by adjusting the size of the orifice in the valve))
