I have narrowed down my suspension refresh for my 340ix to Koni Special Actives and either the E10-20-031-05-22 prokit springs or the E10-20-031-06-22 (Slightly less lowering upfront vs. the "05" version).

Does anyone have pics, measurements, feedback on either? I am leaning towards E10-20-031-05-22, just want to avoid constant bottoming out on NY roads. Yes I will be using shorter f80 bumpstops and all new hardware.

Thanks in advance...pics with either of these (Koni+Prokit) would be extremely helpful.

6-22, higher front spring rate for x-drive transfer case(weight), not as low(as 5-22)
5-22, slightly lower than 6-22 up front. some have on x-drive although it is their RWD kit.
rear springs are the same for each kit, thus same rear lowering at rear

Thank you, but I have done a ton of reading around this and that's not 100% accurate. The RWD 340i springs (eibach p/ns front F11-20-031-02-VA, Wire diameter: 13.0mm, Length : 247mm and rear F11-20-031-01-HA, Wire diameter: 14.0mm, Length: 294mm)are different from AWD variants, both in length and spring diameter.

The 5-22 and the 6-22 are both spec's for x-drive vehicles, but as you mention the only difference between the two being the front springs

5-22 front = F11-20-030-03-VA, Wire diameter: 13.2mm, Length: 235mm
6-22 front = F11-20-031-06-VA, Wire diameter: 13.2mm, Length: 250mm
5-22 and 6-22 rear springs are F11-20-031-03-HA, Wire diameter: 14.2mm, Length: 300mm

I am hoping to find some better comparison photos with the 5-22 additional 15mm drop upfront and paired specifically with Konis (as Billy's tend to add a bit more height upfront). The more I think about it, I feel like the 5-22 if for B8s while the 6-22 is for Konis, since Eibach says they achieve the same lowering...lol

This is what happens when I over analyze

[alohasurftoad]

i have a m-performance suspension so my limited knowledge on Eibach, Koni and suspension in general, comes from what i've read here...

johnung told me he's considering going from 6-22 to 5-22 or possibly a complete change to KW coilovers. maybe he can chime in here as he's done a lot of suspension research has a lot of info from FaRKle! and is an admitted "over analyzer" also, lol.

All good and I do appreciate it. That's what this forum is for I Have read countless threads from both, very very helpful, although there is misinformation sprinkled in-between. Including posts from others that show photos of the 5-22 setup and then just go on to selling them and me not really being sure if they ever installed or ran them on a 6cyl awd vehicle.

I know my real answer is to go KW Street comfort, but I prefer the reliability and ease of set-up in a traditional spring/strut combo, coupled with getting the most comfortable "lowered" ride. I know lowering and comfort do not necessarily go hand in hand, but would love to land at the right 10-20% firmer than stock balance.

My buddy has a 328dx on KW v3, it's not for me...potholes hurt in that thing.

You're right. Both sets are suitable for x-drive. Eibach's online catalogue is very informative.

Absolutely...other than the amount of lowering they have listed for the to sets are the same...lol

I have the 05-22 springs and Koni sport yellows for my 435d Gran coupe but they’re currently in my garage waiting for me to fit them. I did ponder the 06-22 springs for the reason of less front drop but technically the 05-22 kit seems to be the one listed for my car.
If I decide it can take being 15mm higher without looking bad then I’ll potentially change the front springs again.
I’ll post before and after pics and measurements when I do fit them but suspect that could be a few weeks yet.

Much appreciated. I will be sure to update this thread with before and after pics, regardless of the direction I ultimately go

Here are before/after/side profile pics of my 335i XDrive with Koni Special-Active and Eibach E10-20-031-06-22 springs. Started from non-adaptive/non-M Sport stock suspension. I had them installed back in November along with new monoball front upper and lower control arms, front and rear sway bars, and end links.

Like you I settled on the Koni/Eibach setup after reading multiple reviews that they would add a lot of performance upside with a mild drop, while maintaining everyday drivability...which for me is especially important in the 3 1/2 season urban environment I daily drive this car in.

I still need to post a review of my suspension refresh, but I can say after 4 months I'm very happy with the Koni SA/Eibach 06-22 combo. As many on the forum have remarked, this setup on an XDrive gets you to the approximate ride height and fender/wheel gap as a non-XDrive...which was exactly what I was looking for. Visually the car definitely looks lower than before...but not "lowered" if that makes sense. I'd say Eibach's advertised -0.8" front/-0.6" rear drop is accurate. Unfortunately I didn't take before/after measurements but hopefully the pics are informative. In terms of performance, I've seen a significant and very noticeable upgrade over the soft/bouncy factory ride.

I have noticed I'm more susceptible to scrapping the underside of the M Performance splitter on my front bumper, especially going in and out of parking garages. It's not a huge issue, just something I've had to become more mindful of...and it's easily mitigated by slowing down or approaching/departing from an angle. Lastly, I haven't experienced any bottoming out/rubbing. Roads here (DC) are decent...not great, not terrible...but like most mid-Atlantic/east coast cities potholes can be a major issue after snowfalls and plowing. I'm careful to avoid those as I'm sure most of us here are.

Super helpful! First, that's a great color combo Second I really wish I could get a clear shot of that front gap. Yours looks pretty darn spot on. I guess I am now second guessing myself with the 5-22.

My old e90 was on prokit springs and koni yellows and one downfall was that the front settled way too much...decisions, decisions :>). Anyhow much appreciated. This is exactly the type of feedback I was looking for and hoping to compile for others in a similar quest.

[GuestBen]

You bet. Just snapped these a sec ago...

[dmanb2b]

If I could hit appreciate 100 times, I would. That's great...now I'm back to where I started. I think I may just take a shot and go with extra 10-15mm lower springs...haha. Hopefully we get a few more posts here...I have another day or two until I finalize my parts list.

Again, thank you.

[Dave340]

GuestBen I agree with dmanb2b appreciate your feedback and the pictures, this is a great help!!

Sounds like H&R sway bars have not been an issue?

OP I am like you, over analyzing, but I don't want to make the same mistake when I put on H&R springs on my previous F30 328i, it was just too low and did not like the ride.

[GuestBen]

dmanb2b happy to help, good luck with the decision!

Dave340 I saw your reply/question on my first thread (https://f30.bimmerpost.com/forums/sh...hp?t=1872255); regrets for not replying there. Bottom line the misses can't tell a difference at all. Then again she drives the car 1 day a week on average, me every day. And she probably doesn't drive above 40mph. So everything's relative of course...to me the package of upgrades makes a massive difference in overall driving dynamics/feel.

Specifically on the H&R sway bars...they virtually eliminated the excessive slop and body roll the stock F30 suspension is infamous for. While my only other reference point is the stock setup, I haven't found them harsh or overly stiff at all...even with the monoball (SPL) endlinks I combined them with. The car is orders of magnitude more solid feeling and planted in high-G cornering.

Not specifically what you are looking for unfortunately but here is my F36 lowered with the 05 kit & F80 bumps last month.

Well, I am a big fan of the color! How are you liking the setup so far and what struts did you go with? Anything you would change? I really like the look!

My 4x4, on stock suspension for reference...lol

Yes, I have a 2015 335ix with KoniSA's and Eibach -06 kit right now. It's looking like I'm going to swap in the Eibach -05 springs when the weather warms up. The rear springs on the two kits are identical.

The front springs have exactly the same spring rates so the ride should essentially be the same. The -06 lower the front by 20mm under stock. Accordingly Eibach tech support the -05 front springs should drop my front by another 15mm.

At the same time I'll swap in the F80 bump stops and change out the rubber spring perches that have 8 years on them.

[MTTH]

Mineral Gray is such a great color. I stress way less about keeping it clean vs my Black Sapphire E90! So far it's great, it's pretty much like stock honestly just lower with less body roll. I have the M adaptive suspension so I kept the struts since the car only has 11k miles.

I do wish it was just a little bit lower but I want to see how it looks once I do a wheel stud conversion, get some spacers and throw my 19s back on.

Definitely better than before though. Here's my F36 before the springs with the 4x4 package (lol) & 19s on.

From what I can tell from GuestBen 's photos, I think it's obvious that the 6-22 kit doesn't eliminate the reverse rake look completely. I think the 5-22 will have a better result in looks without any difference other than the reduced travel, so I would agree with you and go with the 5-22 kit.

@GuestBen : Yours is Tansanite Blue, right? I have the same colour and it looks amazing under proper light.

Close...it's Imperial Blue Metallic, with Saddle Brown interior. Car started out as a Luxury Line; I went the full M-Sport conversion route before diving into performance mods. Tanzanite is a beautiful color as well...
