I put the Eibach pro kit lowering springs on my car tonight, and it dropped the front perfectly level side to side, and the rear only went down about 1/4", but the pass side is 1/2" higher than the drivers side. I swapped springs side to side, and the pass side is still higher, i put the stock springs back in and its STILL 1/2" higher... is this normal?? can someone measuer the rear of their mach?
