Koni yellows front adjustment - BMW 3-Series (E90 E92) Forum

HermanL · 01-21-2012, 11:45 AM

I was trying to adjust the shocks to correct rebound before I install them, I was able to pre-load the rear, turned it to fully stiff and dial it back to my desired stiffness, but it seemed there is no fully lock position for the front? I did load the front strut to max compression and tried to turn it, but it's turning forever. I searched around but I can't find a lot info on how to adjust the front. thanks in advance for any input

The fronts are adjusted via the valve adjuster on the top of the strut. you should have received a plastic knob that fits on the top of the valve that you can turn.

I do have the knob, but are the fronts suspposed to have a lock position like the rears? mine keeps turning, how i suppose to know when I am at fully stiff or soft?

Thanks

The strut adjustment should stop at full soft and full stiff; about 2 1/2 full turns

Just want to confirm again, no pre load needed to adjust the fronts? is it possible the shocks are damaged and not adjustable anymore?

I've only adjusted them preloaded/installed. Are they not on the car yet? did you buy them new or used?

It's not on the car yet, I bought them used from a forum member here

Mike-y might know or one of the vendors. I didn't try to adjust the front struts prior to installation. The rears you do adjust prior to installation. I suggest 3/4 turn from soft for the rears if you have oe springs. My tech said not to set them at full soft, full firm or 50%

Yes, they should have a lock position at both ends of the range. It sounds like they are damaged.
