Uneven Lowering with Eibach Springs

Hello all. Hoping someone can help or give advice of what to look for. A little over a week ago I installed Eibach prokit springs on my 08 E90 335 xi. It took longer than I would have guessed but in general not a bad DIY. I have driven a few hundred miles and had the car aligned. Handling is nice and the stance in general is nice, but I noticed last night that my driver's side front sits about 1/2-3/4" higher than the passenger's side front (measured from fender lip to top of center cap). I would have thought that by now the springs would have settled so I am trying to think of what would cause one side to be higher than the other. Same installation procedure for both sides though on the driver side I did have to reset the spring compressors after I tried to install the spring on the strut and realized I couldn't get access to remove them... Also it seemed like ther was more man handling on the drivers side to get the strut back in place etc, but this was the first side I tackled so I assume there was a learning curve. Any ideas?

are you 100% sure that you seated the strut into the lower spindle completely after installing the spring?

It's normal for most lowering springs. If you want them to be exactly even, you need coilovers that allow height adjustment.

i think even at oem the front is slightly higher due to the anticipated weight of the driver when you're in the car

I actually left the strut attached at the hub. I broke things loose at the top of the strut, disconnect the sway bar endlink and articulated the top of the strut outside the fender. Just allowed the hub, caliper etc to sag to make enough room to clear the fender. To be honest though I didn't look to see how the strut attached so maybe I loosened something without knowing it. All appeared to be tight. I will take the wheel off this weekend and take a look.

The factory suspension is designed to ride higher on the driver's side however this difference is a few mm at most...this sounds like an install issue.

Any idea what the install issue could be? The spring seems to be seated and the top of the strut went back together. I didn't take any of the bottom of the strut apart or any of the lower suspension. I am not saying I didn't screw something up, but at this point I am not sure what to look for.

mine sits level on both sides with the eibach pro kit i installed.

i would double check the spring to assure its in the rubber sleeve properly/completely seated at the top and bottom.

Try measuring the wheel gaps while parking at different locations. Your garage or parking spot may not be exactly level either. The best place to measure is an alignment rack.

I figured it out. Installation error... Sexe92 had it right. The strut was not fully seated in the spindle. Seated it and the ride height is now how it should be on both sides. Thanks everyone for your help.

Unless it is really bad, it probably is BMW suspension tweaked for driver weight.
