figuring out what springs i have

[Crushbone]

ok, ive been having some suspension problems. im bottoming out occasionally, more often on the driver side (which seems to sit about an inch lower). i have blue tokico struts in front and red kybs in the back, which i am sure of. supposedly i have eibach springs all around, but i am not positive yet (all suspension was installed under previous owner). does eibach springs have certain markings for which spring set or height they are? bc of the bad squatting on the left i believe i need new springs(as well as the bottoming out). i would like the car to still sit lower, but higher than it is now. advice?

I bought my car with Eibachs and all they said on them was the brand name.. sounds like the strut is toast more then the spring all the spring really does is stop from bouncing after hitting a bump.. If its sitting lower on one side thats where id put my money too.. Pull the struts out and push on them either way you need to remove them so why not just do it now. I put on KYB struts and tuned by matrix lowering springs and the cars a little stiff but it rides ok and handles absolutely great..

Eibach would be stamped on the spring and iirc if they are red - sportlines, black - prosports.

the odd thing is, is that the kyb strut in the back on the drivers side isnt even a year old yet...could the front drivers side just be pulling it down some since it seems to sit the lowest (i cant fit the large knuckles on my hand between the tire and the fender, same on the rear though a little higher, and prob 2 fingers for both tires on the passenger side).

If your front shock is bad then it will pull down the rest or that side of the car do to the rear shock has to compensate for the added weight. The front of the car has more weight so its more noticeable if the rear was bad you would be able to tell but not as much due to the lack of weight in the rear of the car.

And the Sportlines are a relatively soft spring. More for lowering than performance. Does your car do a lot of bouncing? That can be a sign of a blown out shock that isn't doing it's job anymore.
