hey, i will be running this setup on my 2011 m sport 335i xdrive e90, just wondering will the bilstein bump stops be ok or do i need to swap them out with something else or trim them????

also i read in some spots, taht there are headlight problems with a leveling sensor. will i have this problem ? if so what will the proper steps be to fix this?

last but not least, how will the camber and toe be after the alignment? i can deal with a little bit of negative camber but dont wnat to go thru tires every year for no reason! lol...

any help would be appreciated! thanks

Good questions, I am curious as well as I will be running H&R Sports...I haven't heard anything about trimming bumpstops or upgrading, I think you'll be ok in that respect.

No idea about the other items though..

I'm considering bilstein with eibachs since H&R may be too aggressive for NY roads.
Also I am under the impression we need to buy new bump stops.

i doubt that we will need new bump stops, my bilsteins have there own bump stops, but who knows, its a slight drop not crazy......

On the front struts the Bilsteins have their own bump stops INSIDE the strut, at the bottom. The shaft diameter is far too large anyway to use conventional bumps, as you will find out when installing them. See pic here:

hmm so does that mean the ones it comes with for front and back are ok to use? we wont be needing m3 ones or anything of the sort???

On the fronts it is not possible to fit other bump stops on, the ones that come with are inside the strut anyway. The rears you can use whatever you like. I have not installed bilstein sports on a e90 myself so I am not sure what exactly the rears come with, if anything. I'd say if they come with something use it.
