Default Uneven lowering? Bilsteins + Eibachs

How low is your car after installing the Bilstein shocks + Eibach springs?

I installed the "B12 Pro-Kit" and my fronts are much lower than my rears...see below!

Will the rears settle and get lower? There was a period in between installing the rears and fronts when the car was resting on the front two wheels with the rear of the car suspended on jack stands...for about 12 hours...maybe that makes the difference I'm seeing? Here's a picture today

That front drop looks too severe..
As a comparison, I have H&R Springs which drop car 1&1/4" and should be even drop front and rear.

I might give it a few days to see if the rears "settle"...?

I'll change up my front control arms. They might be my problem.

When installing the shock absorber, did you tighten the clamp nut (sway bar link) before lowering the car? Failure to do so would bend the tab holding the shock at the right level and allow it to slide too far into the knuckle.

For the rear shocks yes I loosened and tightened the sway bar during installation when the car was in the air.

For the front shock installation I I did remove and (before dropping the car) replace the sway bar end links.

I get what you mean, there’s tabs alongside the fin that sticks out from the strut body and there’s a hole in there that the sway bar end link goes through.

I'm no expert but I'd focus on fixing the fronts. That looks way too low for this setup.

Did you buy all these parts new from a dealer. I've never seen red Bilstein shocks - just blue, yellow, or silver.

I switched to the B12 kit from H&R springs last year. I can't remember the measurement in the front, but your front does look lower compared to mine.

Known issue with the Eibach springs on our cars. I had the same B12 kit on my 997.2 and the uneven drop always irked me. The performance of the kit was great, but that one thing made me wish I went with H&R springs.

For sure the Bilsteins were shorter than the originals.

I hadn't read that there were known issues...just that the Eibachs were less of a drop than the H&R's.

Nope the rear won’t settle.

My Eibach springs are much lower in the front.

If I keep my car much longer I am going Feal/Swift or BC Coils to get some lift in the front, and dampening adjustment.

Your stance looks very even. Looks good to me. Your front doesn't look too low.

I took photos this morning...all's looking good, no loose fittings or detached parts or sunken shocks or torn upper bodywork where the screws attach, etc...
