Need to replace front struts on my '17 240ix. Wanted to upgrade over stock to take care of the instability over expansion joints etc. Article I read said the Bilstein B6's were the upgraded shock that still kept the other functions and variable damping.

Now that they are installed it's like sport mode all the time. I feel zero difference between eco, comfort or sport.

Anyone else running B6's how do yours feel?

Edit: put a few more miles on it and it feels slightly better. But still not much difference in modes and mostly if pushing a corner. Still harsh for eco or comfort mode. (Sorry about the overdramatic verbag before)

They do feel like an upgrade and if they breakin a bit they should be an upgrade. Thoughts?

I’m running b16s and they feel like an upgrade over m suspension

You mention they retain variable damping. Did you buy the B6 Damptronics?

I have the b6 damptronics on my car, they are stiffer across the board, and I'm pretty sure they lifted up the ride height a bit. They're fantastic on track though.

I have the B4 damptronics on my M235i and they too are rather harsh. A lot more NVH, especially over high freqency road imperfections. However the car handles really well. Can get tiresome at times. Mine definately raised the ride height by about 8-10mm. Sometimes in Sport mode I can feel the rear rise slightly.. not by much though

I replaced the OEM Damptronic shocks at 90,000 miles with the Bilstein B4s. I would have done them sooner but the shocks were hard to find. I labored whether to get the B6s but I find the B4s perfect in every way. No noticeable NVH and no ride height change.

Just my experience.

Interesting! you look to have the same car as me. I do have M Performance springs on the front which are stiffer than M Sport but also 19inch 624M Alloys so not much sidewall give. Do you run 18 inch wheels? Having said this I went directly from OE Dampers to B4 with the same springs and wheels so the only difference was the B4's and they definately made the ride harsher. Guess this is a subjective subject.
