hahahaha..exactly what i was thinking..
check if its actually the eibach springs and not the OEM ones

 

yea....that happened to me as well. Bought them from a member of this site. They were shipped to me in an Eibach Pro-kit box. Didnt even think to check them, so I took them to a shop to get them installed. After they completed the front ones, we all noticed that they were all OEM springs. So i had to pay for the labor in front. Luckily, the seller gave me a refund, so I guess he made an honest mistake. Sucks that I lost money on the labor and shipping the OEMs back.

 

You should have noticed right away.

I did my Prokits and Dspecs at the same time. When I lowered my car, I noticed a drop right away. Nothing crazy but noticeable. Then it got lower and lower as time passed. Now I swear it looks like it dropped 1.4" front and 1.25" rear.

 

Measure a stock G35 and then measure your car....If there's a difference of an inch or close then it should be okay. Wait for it to settle...

 

even if the springs hasn't settled, you should see a difference especially if you're running stock tires.

Did you notice any part numbers on the springs??
