So I put a set of eibach prokit springs on and I've run into an issue related to ride height.

Car is sitting on stock shocks w/ eibach springs, 2006. Square stance 245/40/17's on ap2v1 wheels all around. Important note: 125k miles

The springs have been on for about a month now, and I've noticed my ride height isn't consistent. Everything was preloaded properly and I'm positive all the springs are seated correctly as well.

Measured from the lower lip of the centercap of the wheel:

Passenger rear: 15.5 inches
Driver side rear: 15.5 inches
Driver side front: 14.5 inches
Passenger side front: 15 inches

Is it normal for the rear to be about a half inch higher than the front with eibach on stock ap2 suspension?
What is causing the driver side front to be an inch lower than the rear and a half inch lower than the passenger front? My only guess is that I'm just an idiot for putting springs on shocks with 125k miles on them and that's where my issue lies.

I'm currently in the process of replacing all my seized alignment bushings (fun), so I'd love if anyone has any advice or experience with this ride height issue and what I should do next? (My guess is buy new oem dampers) Kinda want coilovers, but I daily drive through the winter, and I'm afraid of corrosion issues.

 

Springs dictate your ride height even though these are monotube shocks.

I'd assume that its pretty normal for the rear to sit higher. The rear suspension is limited for travel. But you have a 1" difference when looking at the LF.

Has the car been aligned? Camber adjustments can have small effects on height.

What is the advertised drop on the springs?

125K miles may be pushing it for the shocks. I'd try to find a nice used set if you're still trying to stay cost effective. Though...something like Koni yellows will also work with prokit springs.

 

I have the eibach pro kit and the rears do sit a little higher than the front. Just eyeballing id say around 1/4 a 1/2 inch higher. I didn't really notice any left-right inconsistency though, but then again I didn't measure either

 

OP...was your car on a level surface when measuring? Your driveway is likely not level. Your concrete garage floor *might* be level. An alignment rack is level.

 

These springs look very similar front to rear. Make sure you don't have them switched. Front spring part number ends in "VA" and rear spring part number ends in "HA" for reference. Good luck!

 

Yesterday by curiosity i measured my S2K and i also found that i have different height on each wheel. And i also have eibach springs..

Going to take the car to the mechanic and when i have feedback i will let you know!

 

Fenders are not a reliable place to measure ride height. Measure from the pinch welds.

 

Thanks for all the replies everyone

As for the alignment question, funny you ask, the camber bolts in the front are some of the seized bolts so they have not been aligned yet. Currently at FL: 1.2 negative and FR: .8 negative. Not sure that .4 degrees of negative camber would amount for a half inch difference (or so) in ride height though? Thoughts?

For the level surface or not, yeah it's certainly not a perfect surface (being my garage), but I've measured backed in and pulled in and have the same or very close results. This is a difference that is noticeable from simply looking at it, regardless of where I park. I also understand my method for measuring isn't perfect, it was just to give an idea of how much lower the front left is from the front right.

My plans are to just find some decent used shocks as to replace these, but I am still concerned that the problem will remain. Other than more feedback from you guys I suppose the next step should be to contact eibach about the issue, although I just don't think it's anything wrong with the springs.

 

It should be noted that the car doesn't weigh the same from corner to corner.

Taking wheel rates into account, 100LB may be good enough to make a 1/2" difference.

My suggestion....sell the springs. Buy a set of Bilstein PSS or H&R SP coilovers. Or if you need to drive the car in salty conditions, Tein Street Flex or Flex Z coilovers.

You'll pay a bit more...but you will be happier with the outcome.

 

I'm having similar issues with my Eibach Pro Kit. Seems to be a common issue? :[ Saving for a set of Bilstein PSS as mentioned by B serious.

Goodluck!
