Anyone else have springs that continue to sag?

CarbonFoot · 10-31-2012, 05:06 PM

I installed a KW sleeve kit early this year and I immediately setup the ride height to be -1"F and -.75"R from stock. Within 2 weeks, the springs settled a little less than .25" in front and little more than .125" in the rear. I then readjusted to bring it back to -1"F and -.75"R and got an alignment done.

So it's been several months since making those adjustments and my car is sitting lower than ever now at -1.25"F and -1.125"R. That's another quarter inch sag in the front and a considerable half inch drop in the rear.

Has anyone else experienced this with KW or any other manufacturer for that matter? Some settling is definitely expected, which is why I waited a few weeks to make my first adjustment. I guess I just didn't expect to need to do it again.

I have the same kit and I could swear mine has been getting lower. I thought I was crazy...

^^ You're definitely not going crazy. Fortunately, I took very careful measurements along the way to verify that I wasn't going crazy myself.

Hopefully after my next adjustment, enough time will have passed to fully settle the springs and they will stay relatively stable going forward.

Give KW tech support a call at 800-445-3767 (8-5 PST) and perhaps they can help you.

Not a bad idea. I doubt they'll be able to do anything, but at least they might be able to tell me if I should no longer experience any further settling. Thanks...

Assuming you have a 2012 judging by your join date, the oem rubber top mounts sag over time which could be your problem. This is just a guess tho.

I've never experienced spring sag or even settling. I've played with a few brands of springs on 2 generation M3's, never went the KW route though.
