Rear spring heights.

I've had my 92Z about 7 years now. I put the stock springs back into the front. I just took the Eibach lowering springs out of the rear to go back to stock ride height. With the rear springs sitting on the floor, the Eibach's and the stock springs are the same height. Shouldn't the stock ones be taller?

Re: Rear spring heights.

I'm not sure about the heights but the stock springs will compress more then the lowering springs due to the lower spring ratings.

Re: Rear spring heights.

I talked with Eibach and gave the serial number off one of my springs. They said it should be about 10% stiffer that the stock springs. But when i lean on both the stock spring and the Eibach one, the stock spring definitely feels stiffer. Both sitting on the floor are about the same height. Thanks for your reply.

Re: Rear spring heights.

There is a section of closely spaced coils at the top which is the take-up portion. The number of coils & spacing effects height & spring preload. Theses coils touch with weight of car on them. After weight is on the car, you then get the effective spring rate. You would need to put about 700lb on each & then compare the height to get an idea of the true compressed height.
