Eibach prokit lowering springs problem..

In my experience, the Eibach springs have always been very consistant with their kits. I would suggest doing one of these two things or both.

Depending on how the suspension was installed and what parts were loosened, you may need to preload your suspension and retorque your control arm bolts. Some shops will remove or loosen upper and/or lower control arms during suspension install then torque down the arms while they are at full droop. This puts pressure on the bushings and does not allow the suspension to fully settle. The proper way to tighten these bolts is to have the control arms pushed up to static ride height and torqued.

The other option would be to switch the springs from left to right. This would require completely disassembling the springs from the shocks and switching the springs around. If your ride height issue stays on the same side then you know it's not a spring issue. If your front right raises 10mm then you know you have an issue with the spring.

Good luck!
