Why is one side an inch lower? Eibach sportlines

I added a set of new Eibach sportlines to my 88 gta and the sides are not even height. All numbers are inches from ground to tip fender lip. It has about 100 miles on them since install. Springs all got 1 layer of rubber hose wrapped to the top. Driver front 26" Passenger Front 27"
Driver Back 27" Passenger Back 28"
Is it possibly a shock issue? I tried to install the front strings in the exact spot between the two holes to try to prevent this.


High side

Low side

Driver front 26" Passenger Front 27"
Driver Back 27" Passenger Back 28"

Re: Why is one side an inch lower? Eibach sportlines

I've had a few thirdgens in my days and I've NEVER had both back left and right, and both front left and righ the same height. That being said, 1" is a lot, and having it both on the same side front and back is strange. If you take into account how much these cars flex, it does make sense. Still...your situation is strangely uniform. I don't have a good answer for ya.

Can you measure from the ground, up to the bolt where the front control arm bolts to the frame/K-member? I had my 13 year old help me as I couldn't squish under the car with it loaded on the ground!!!

I would take a hard look at the passenger rear. If that's high then it will change all the corners but especially cause front diagonal to compress, which kind of seems to be the case.

Wow, and I was upset about the left front being a quarter-inch higher than the right front...

I have sportlines in my car and everything is fine except the drivers side front. It’s about 1” lower then the passenger side front. Drives me nuts

I'm going to pull the back passenger side and check it out again. Hoping I can get an inch lower out of it somehow.

I just had a similar issue. One of the springs wasn’t seated in the pocket and it pushed that side up about an inch.
