Before I pull the trigger on the Bilstein, just want to confirm that the correct part number is 47-264625. Bilstein didn't list the wagon on their site so I chose the GT.

After pouring through the entire thread I decided to go the Eibach E10-20-031-14-22 springs and Bilstein B6 route. I wanted only a moderate lowered stance, nothing too crazy, but was after driving characteristics with better damping at sudden load changes and less body lean in corners. This setup works pretty well for me and I am happy with this setup.
The old struts were in bad shape. As a matter of fact the driver side strut was so weak that it compressed on it's own weight when set upside down on the ground. The rear shocks where slightly better, but not by much. Then again these components had the original 120k miles on them, so it was time for a change either way. Did the work myself thanks to FaReKl's great video, the only thing that gave me some trouble was the rear camber arms and getting the camber arm bolt back in and aligned. I ended up having to use a strap ratchet set to pull the arm towards the front of the car as the spring was fighting me. Got the springs from ebay from a German supplier directly as there seems to be a shortage of the E10-20-031-14-22 and -15-22's at US retailers, whereas the B6 set I had no issue sourcing.

H+R coilovers are on and I love the ride. They’re very good at soaking up the small stuff and the car feels well planted when cornering.

I had the Eibach 14-22 springs installed in my 2017 F31 yesterday and I couldn't be happier. It's the perfect amount of drop I was looking for, just enough to minimize the big gap of the stock springs. The ride feels good, a little bit firmer than stock but not harsh in any way. I kept the stock dampers, the car only has 30k kms. The floaty feeling is gone and just feels and looks like I thought a bmw should now.

Here is mine with the Bilstein B14 installed. It is around 1" drop on all 4. After the break in, the ride is firm but not harsh. Liking it so far.

Just bought a 2014 F31. Car is already lowered on eibach springs. Can anyone verify if these are the correct springs for a 2014 F31 with sport package. From the front springs I can see the numbers
Front springs: KBA 91389/ 91390 11 2003102 VA Also, they ride rough.....maybe need new shocks. What is the correct part numbers for Bilstein shocks? Last edited by the1obster; 11-14-2021 at 09:32 AM.. |

Hi all. I have a 2014 F31 with active suspension, and replaced my fronts with Bilstein B4 Damptronic units last year, and now need to replace the rears. Unfortunately the matching rear units I ordered in September are now backordered until March of 2022.
I am only looking for OEM ride and height. Can I install the regular B4 (non-active) shock instead? |

Try reaching out to andreas.schade@gmx.de. He's a European Bilstein vendor that I've purchased items from before when US vendors didn't have any stock. Sometimes his prices have been better than US vendors too even after shipping.

My 2017 330i came with BC Racing coils from previous owner. I probably wouldnt have gone with a 1000.00 coilover package had I been making the initial call, but thats what we've got. Thunking noises at slow speeds from both fronts as well as rear passenger. Looks great but driving me crazy...the more f31 owners I talk with, the more I hear have the same low speed issue with knocking. Wondering if its just springs slipping out of seating position or something that is happening regardless of brand/setup.
Don't need a tucked/slammed look - probably wont track the car...thinking maybe KW street comfort to keep it under 2k if I replace the BCs? Anyone have experience with the flatout SR or other options in the sub 2k price? Current height: |

No knocking here with Street Komforts. it is a little Thumpy in the front at same ride height over bumps, think you start running out of travel when this low.
I’m about 1/2”-3/4” higher in rear with rear adjusters all the way down. No issue with ride comfort rear at all even over bumps and heaves. When I was at a higher ride height in the front I didn’t have the thudding over bumps either. Maxed out front I was about 1/2 lower than stock all around and it rode better than stock. Thinking about raising the front up 1/2”… just haven’t bothered with it since I know where all the bumps are now. That was as low as I felt comfortable going and still keep some preload on the front springs.

After 5 years and 52K, I'm starting to look into suspension upgrades for my F31 w/ EDC. I guess I'm more motivated now because suspension components are not covered under CPO, nothing to void!
On top of that, I had a chance to drive stock G20 330i and F44 230i GC loaners and felt they handled much better. There was no body roll in corners, I felt planted to the ground, steering felt more precise, and felt like I wasnt pulling any lateral Gs. On my F31 even with non-RFTs@+2 PSI, EDC in Sport, the body roll is really noticeable. What I'd like to achieve is:
I've been searching through the community and narrowed it down to Add front strut bar Considering the low cost and easy DIY, is this really the low-hanging fruit? Replace shocks w/ Bilstein B4 or B6 Damptronic units (stock springs) I'd be replacing all 4 strut mounts too if I were going this route. I've been hearing a lot of good things about the B4s and heard they do help address the body roll. The B6's I've also heard good things, but they can be more stiff that stock and maybe overkill for what I'm looking for. Are the B4's good enough? Also open to other suggestions. Considering I'm not a suspension guru nor a avid modder, I cant tell if shooting for loaner-level handling is setting the bar too low or too high.

Front bar adds understeer, rear bar over steer,
Staggered rear wheels adds understeer, square reduce it. I’d add a rear bar before the front, as that is the higher cg end of the car and IIRC the one with the lower effective spring rate. Certainly is the end my highly developed chassis dynamometer (backside) says needs the bar. But I’d honestly do both at once if square. On the e34 tourings we would upgrade rears to m5 or m5T Nurburgring sways, sadly nothing like that for f31 and you have to drop the subframe. Recommend watching FaRKle! videos on YouTube. The guy knows of what he speaks and breaks it down well.

I ended up installing a Megan Racing strut bar, since it was relatively cheap and they were local. Installed new bolts and TTY. Steering seems improved and more precise, the car reacts better to small adjustments from the steering wheel. However, there's only a small improvement in body roll. Going into this, I wasnt expecting a drastic change and for the $90 price tag, I'm not having many regrets.

What is the equivalent setting (Comfort or Sport) if use B4 non EDC in EDC car?
Its a thought changing to non EDC due to availability (Self import) and pricing (5x price) Last edited by free2d; 01-30-2022 at 05:49 AM.. |

Now that I got rid of the 400m and pirelli run flats for 19s and dws06 go flats… no more issues with thumps or thuds over bumps/manhole covers /broken pavement. Even at 1.5” down in front and 1” down in rear on KW Street Comfort.
