Strut assembly Bilstein or KONI
B8's are great. I run them on my MK7. But they need to be paired with more aggressive springs as the B8's are a shorter & stiffer strut. So softer springs will often bottom them out.
Like H&R Sports. Those are a popular combo with the B8 strut.
Yes, you'll notice a difference. As the car will have proper damping. Ride won't be as harsh, bumps won't be bouncy, cornering will be more definitive & sharp.
Bilstein B4/B6 struts are designed for stock springs and really drive the performance upmarket. Last, buy new stock endlinks and get a 22mm solid rear sway bar. You can do all that for <$2K and the car will drive like a 50-60K performance car until 200K miles with no notable maintenance increases.
I run bikstein b8 struts with eibach sportline springs. Definitely feels like it hugs the road a little better, less bouncy, and just feels better overall. I didn’t really notice a drop in suspension compared to when I just had the springs on. I’d say worth it if you’re not going to use the adjustability of coils.
I don't trust brands like Monroe or Duralast, so I was going to order some Bilstein B4s ($65.00 each) and re-use my old springs.
Consensus on OE replacement, same ride height is OE or Bilstein B4s, about 10% stiffer. Alltrack specific B6 came out, finally, in front struts about 8 months ago, but are sold out
I put h&r sport springs with standard Bilstein struts on my touring a few months ago
Sits mabye a hair lower than a stock non-xi car
Should be a pic in my history if you want to take a look
H&r springs, Bilstein struts & shocks
That’s what I have on my 325xi
Get bilstein struts. Suples springs. Lemforder bushings. Lemforder tie rods and ball joints.
The Str.T is fine for a mild upgrade over OE. I've had them on my car for about 10 years now. I live in Texas, so rust is not an issue. However , if I were doing it all over again, I would spend more for the Koni Sport (Yellow), as I think the Str.T is a touch softer than I would have preferred.
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.
