Eibach prokit lowering springs problem..

Maxi

Hey,

Has anyone had any problems with lowering springs in 370Z?

Couple of weeks ago local workshop installed springs to my Zed and there are differences in height, especially drivers side and near side of the car.

Example: (measured from center of the wheel hub to wheel arch)

Front left 345mm
Front right 335mm
Rears 355mm

Eibach reports that it should be about 360mm at front and 357mm at rear. So what actually can cause problem like this? Problems of the hardening of springs? Defect product? I also remember that i have read that someone else had experienced that these springs lower more than eibach informs.

Local shop who did install job did everything right (at my opinion) , as i was watching the install whole time.. Springs are in right position in lower mount (cup) of shock and everything looks ok. And yes i have double checked codes and they are right in springs and in package..

I suppose that shock struts can not be installed incorrectly?

Any advices are welcome.... Thanks.

Edit: Car has only 12000km and oem shocks were in good condition.
