Strut assembly Bilstein or Sachs

The B8's pair REALLY well with the Neuspeeds. Ride is actually less bouncy and the struts dampen better and faster. Bumps in the road that use to be pretty jolty are less of an issue, and body roll has been reduced significantly. My turn in bite feels a tad sharper and the car feels and stays planted very nicely compared to the OEM struts.

I have stock springs with Bilstein B4 struts and shocks. Roads here are not great, so I didn't want to lower the car, but I wanted better ride and control than the mushy stock suspension. Hated the porpoising on the freeway when I bought my car. The new shocks give a much better ride without being too harsh for the family. The car feels German now instead of like a Buick.

I too have B8’s on mime but use new oem VW strut and bearing. No issues or noises after 10k.

I asked the same question you had several months ago and went all out by picking up Bilstein GTWORX struts and RCE yellow springs.

The Sachs come with the performance package. Totally worth every penny if you like to mod, track, and auto cross. The Sachs struts have different valving but much better performance than base suspension setup. They also work great with aftermarket performance springs (RCE Yellows work perfectly with the Sachs). I have a 2018 BRZ with the Performance Package with Brembo brakes and love it.

I paired Bilstein B6 struts with H&R springs. Absolutely night-and-day. The car feels so much more secure and planted. The B6's shorter stroke and beefier build prove to be a great quality ride, even in comfort and normal mode. There's little-to-no dive, and the front corners are more responsive and poised under load.

Sachs was the OEM for the struts on my old e39 bmw 528i w/ sports package. I had gotten 60k miles after replacing them before trading the car in.

If they are good enough to be original equipment on a BMW they’re probably pretty good.

I went from Sachs to B6 just in the front and it’s meh.

I ordered Bilstein b4 non sport and had a similar result once installed. It still seems my car was non the sport package but that could be the problem. I had found other threads regarding this issue with B4s and some gas struts. They never really settled.

I regret putting B6’s on my 530i, the OE sport suspension rode much nicer and handled just as well.

I also had to warranty one of the front struts after a year due to a clunking noise, apparently it’s a very common issue caused by the inverted design.
