Shock absorbers Bilstein or Sachs

I replaced the Ranchos with Bilstein 5100's after a couple thousand miles, night and day difference.

I went with Bilstein B6/B8's and was pleased with them, but they provided a slightly firmed-up, well-controlled ride compared to my high-mileage OEM units

I have 6112 front 5100 rear and I cannot express the difference in ride quality and even “handling”. Totally eliminated understeer.

I did the Bilstein 5100s and very happy with the result. On a 5.3 truck, the 2" cir-clip setting put the truck pretty level. Rides so much better.

I recently did my shocks and struts from fcp also Bilstein and I have no issues or complaints

I just installed Bilstein B4 kit front and back on my 06 E90 last week. Feels amazing. Wish I had gone with B6 or B8 but the B4s are great.

Bought full Bilstein B4 kit for my e90 w/ sports package. Great kit, came with everything you need to replace and all the smaller stuff like strut mounts etc… highly recommended FCP and the Bilstein replacements as the absolute best replacement for OE suspension. Bilstein is a high quality, reputable brand and well known in the industry.

I used Bilstein 5100 and Old Man Emu medium duty springs on my 04. Very cost effective way to get 2.5 inch lift and decent ride quality.

I put B4's on our 2008 535xi a few years ago. I first thought they were stiff but I decided the old ones were really soft. B4 was listed as the OEM equivalent.

I'd personally recommend sticking to OEM (probably Sachs or Boge). My Bilstein warranty return rate since 2016 is close to 100%. B4, B6, B14. All of them. Quality fell off a cliff.
