Lowering springs without aftermarket struts

I plan on lowering my car, but not by much. Originally my plan was to lower with a good spring + strut combo, unfortunately there arent any for my car and who knows if there ever will be.

Anyway since there arent any aftermarket struts, my only choice is to go with lowering springs.

However I have a few questions

1) Does drop height alone determine the amount of negative camber, and also the amount of stress put on the stock struts?

2) I've narrowed it down to 2 options for lowering springs

a.Tanabe GF210, lowers .8" front, 1" rear
b Eibach prokit, lowers 1.5" front, 1" rear

So would the Tanabe springs put less stress on my struts due to less drop, and be a slightly "softer" ride?

And yes, I realize that staying stock will eliminate all problems/worries of blowing my stock struts

1) It depends entirely on the car but generally speaking with a car that isn't on solid axles you can drop the car an inch or so before a camber kit is needed.

2) The height of the drop doesn't necessarily equally correspond with the harshness/softness of the ride. It all completely depends on the spring rate of both different sets.

What car are you dropping?

I wouldn't go with eibach simply because it puts a lot more stress on your strut compared to the tanabe.

What do these spring rates mean?
For example, the tanabe springs I'm looking at have the following:

Front: 3.9
Rear: 4.7

Jim, I'm trying to find out which between my 2 choices has the stiffer spring rate
Also Im running 18x8's with a +45 offset

I'm trying to choose the right springs so I dont have any rubbing issues or put too much stress on my stock struts
So nothing is for sure yet

the eibach have a progressive rate spring. This means that the ride is softer around town and slower driving. When you push the car on the highway, the springs firm up and there is less lean. If your tires do not rub now and you can put lots of weight in the trunk and on the front and it does not rub, then the tires should not rub when you have lowered springs.

Now, Eibach is a reliable company. If they made and designed springs to fit your car, they made them to work with the stock struts.
